Craft stained glass at home
This curriculum takes a complete beginner from zero knowledge of stained glass all the way through confident, independent home studio work in both copper-foil and lead came techniques. Each stage builds directly on the last — first establishing safety, tools, and glass literacy, then mastering the two core joining methods, and finally developing the design and pattern skills needed to plan and execute original projects.
Lead Came Mastery
Some backgroundCut, fit, and solder traditional H-came and U-came lead panels; understand glazing compound, panel reinforcement, and the structural differences between lead and foil construction.
▸ Study plan for this stage
Pace: 4–5 weeks, ~20–25 pages/day; treat Divine's text as both a reading and a workshop manual — read a section, then immediately apply it at the bench before moving on
- H-came vs. U-came profiles: understanding the structural role of each came type, when to use each, and how Divine distinguishes their application in panel construction
- Lead cutting and mitering: using the lead knife and dykes correctly to achieve clean, tight joints at corners and intersections as demonstrated in Divine's step-by-step instructions
- Glass cutting for lead work: the slightly different tolerances required when cutting glass for lead came (versus copper foil), accounting for the came heart width in pattern sizing
- Panel assembly sequence: Divine's method of building up a panel against a wooden frame — establishing the border came first, fitting pieces in logical order, and maintaining alignment throughout
- Soldering lead came: flux selection, iron temperature, and the technique of tacking then fully soldering joints so they are smooth, strong, and flush with the came face
- Glazing compound (putty/whiting): mixing, working under the came flanges for weatherproofing and rigidity, and the cleaning/whiting process Divine describes to remove excess and harden the panel
- Panel reinforcement: understanding when and how to add steel re-bars or zinc borders for larger panels, and how Divine addresses the structural limits of lead alone
- Structural comparison — lead vs. copper foil: recognizing that lead came is a self-supporting skeleton while copper foil relies on solder seams for strength, and how this affects design choices
- According to Divine, what is the functional difference between H-came and U-came, and in which parts of a panel is each type typically used?
- How does the pattern (cartoon) need to be adjusted to account for the heart width of the lead came, and why does Divine stress this tolerance in glass cutting?
- What is the correct sequence for assembling a lead panel against a frame as described in Divine's method, and why does the order of piece insertion matter structurally?
- What role does glazing compound play after soldering is complete, and what steps does Divine outline for applying, working in, and cleaning off the compound?
- At what point and by what criteria does Divine recommend adding reinforcing bars to a panel, and how are they attached without compromising the design?
- How does the structural logic of a lead came panel differ from a copper-foil panel, and what design or size constraints does this place on each method?
- Pattern drafting drill: Take a simple 12-piece geometric design, draw the full-size cartoon, then re-draw the cut lines inset by the exact heart width of your chosen came — compare the two and verify every piece fits with came in place before cutting any glass.
- Came cutting practice: Cut a set of H-came lengths and miter a series of 45° and 90° corner joints using only a lead knife and a straightedge; aim for zero visible gap when pieces are butted together under a loupe.
- Mini panel build (6"×6"): Following Divine's assembly sequence exactly — border came first, wooden frame stop, pieces inserted in order — build a small geometric panel in H-came, solder all joints on both faces, and photograph each stage for self-review.
- Glazing compound session: Mix and apply glazing compound to your completed mini panel, work it fully under the flanges with a stiff brush, apply whiting, scrub, and buff; note how panel rigidity changes before and after this step.
- Structural stress test comparison: Build two identical small panels — one in lead came, one in copper foil — then gently flex each by hand and observe where flex and stress concentrate; write a one-page reflection on how this informs design decisions for each method.
- Reinforcement exercise: Design a hypothetical 24"×36" panel on paper, identify which lead lines would need re-bar support using Divine's guidelines, mark re-bar positions on the cartoon, and explain in writing why each bar is placed where it is.
Next up: Mastering the structural and material logic of lead came — its tolerances, compound finishing, and reinforcement needs — gives the reader a solid benchmark of traditional panel construction against which more advanced techniques (such as complex curved cutting, three-dimensional forms, or restoration of antique windows) can be meaningfully understood and contrasted.
A classic, widely-used manual that treats lead came as the primary method; its methodical approach to cutting leads, fitting corners, and applying putty/glazing compound is the clearest introduction available.
Design & Pattern Making
Some backgroundCreate original cartoons and patterns suited to both techniques, apply color theory specific to transmitted light, and plan structurally sound panels before cutting a single piece of glass.
▸ Study plan for this stage
Pace: 2–3 weeks; spend the first 2–3 days doing a full visual survey of all patterns in the book, then revisit each pattern family (birds, then butterflies) at a pace of 8–12 patterns per sitting, ~30–45 minutes daily — sketching, annotating, and color-planning as you go.
- Cartoon drafting: understanding how Sibbett's line drawings function as full-scale templates (cartoons) ready for tracing onto glass
- Lead line as design element: recognizing how the bold outlines in each pattern define lead came paths and must be planned for structural integrity, not just aesthetics
- Transmitted vs. reflected light: analyzing how Sibbett's color suggestions and the shapes themselves are optimized for light shining through, not bouncing off, the glass surface
- Symmetry and repetition: identifying bilateral, radial, and tessellating symmetry in the bird and butterfly patterns and understanding why these structures simplify cutting and assembly
- Shape complexity vs. cuttability: distinguishing patterns with gentle curves and obtuse angles (beginner-friendly) from those with tight inside curves, acute points, and isolated islands that demand advanced cutting skill
- Organic form simplification: studying how naturalistic bird and butterfly anatomy is abstracted into a minimal number of glass pieces without losing visual identity
- Color value and contrast in transmitted light: learning how light/dark value relationships and warm/cool color pairings create depth and focal points when backlit
- Pattern scaling: understanding how to enlarge or reduce Sibbett's patterns using a grid method or photocopier to fit a specific panel size while preserving proportion
- Looking at any pattern in the book, can you identify which lead lines are structural (load-bearing) and which are purely decorative, and explain why that distinction matters before you cut?
- How does Sibbett's use of thick, unbroken outlines serve a different purpose in a stained glass cartoon than it would in an illustration meant for print or screen?
- Choose one bird pattern and one butterfly pattern from the book — how would your color choices differ if the panel were front-lit (reflected light) versus back-lit (transmitted light), and why?
- Which three patterns in the book would you rate as most beginner-friendly for cutting, and which three are most advanced? Justify your ratings using specific shape and angle criteria.
- How would you scale a pattern from the book to fill a 12" × 16" panel, and what steps ensure the lead line widths remain proportionally correct after scaling?
- How does the bilateral symmetry common in butterfly patterns affect the cutting plan — specifically, how many unique glass shapes do you actually need to cut versus the total piece count?
- Full-book pattern audit: Go through every pattern and tag each one with three ratings — (1) cutting difficulty (1–5), (2) dominant symmetry type, and (3) a proposed 3-color palette optimized for transmitted light. Record these in a dedicated design notebook.
- Cartoon tracing drill: Select five patterns of varying complexity, trace them at full book size onto tracing paper, then number every individual piece. Write the proposed glass color and a note about cutting challenge directly on each piece — this mimics real cartoon preparation.
- Grid scaling exercise: Choose one bird and one butterfly pattern and scale each up to a target panel size of your choice using the grid method (draw a grid over the original, then redraw each cell larger). Check that your scaled lead lines are between 3/16" and 1/4" wide to suit standard came.
- Transmitted-light color mockup: Using colored markers or transparent watercolor on tracing paper laid over three chosen patterns, test at least two different color schemes per pattern. Hold each mockup up to a window and photograph it — compare how the schemes read in transmitted light vs. on a flat surface.
- Structural integrity review: Pick two patterns with large, unsupported expanses of a single color. Sketch in hypothetical reinforcement lead lines (or copper foil seams) that break up those expanses without destroying the design, then justify each addition in a short written note.
- Original cartoon inspired by Sibbett: Using the abstraction principles observed in the book, draw your own original bird or butterfly cartoon from scratch at a target size of 8" × 10". Apply all planning steps: number the pieces, note colors, flag difficult cuts, and confirm no single piece exceeds a manageable size for your current skill level.
Next up: Mastering how to read, adapt, and originate structurally sound, color-planned cartoons from Sibbett's patterns gives you a complete paper blueprint in hand, so the next stage — selecting, scoring, and cutting actual glass — begins with confidence rather than guesswork.
