What to Do When a Cut Piece Doesn't Fit

Almost every project has at least one piece that doesn't sit quite right against the template the first time. It's normal, and it's fixable, usually faster than it feels in the moment.

Figure Out Which Way It's Off

Lay the piece back on your numbered template and look closely at where it doesn't match: too big along one edge, a corner that's slightly the wrong angle, or a curve that came out straighter or tighter than the pattern line. Knowing exactly where the mismatch is tells you whether it's fixable or worth recutting.

When Grinding Can Fix It

If the piece is only slightly oversized or a single edge is a bit uneven, a glass grinder can usually correct it. Grind a small amount at a time, checking against the template frequently, since glass removed can't be added back. This works well for minor overages, a piece that's noticeably too big in one direction is a sign grinding alone won't solve it, and you'd be removing so much glass that the piece's proportions would look wrong.

When It's Time to Recut

If a piece broke well outside the intended line, or a curve came out a significantly different shape than the pattern, it's usually faster to retrace the shape onto a fresh piece of glass than to try to grind a badly-shaped piece into submission. This isn't a failure, it's a normal part of the cutting process, and a clean recut takes less time than an extended grinding session that may not even succeed.

Small Gaps Aren't Always a Problem

A very slight gap between two pieces, smaller than the width of your foil, will often close up once both pieces are foiled and soldered, since the foil and solder bead add a small amount of thickness along the seam. Don't over-correct minor gaps before foiling, you may be fixing something that resolves itself in the next step.

Preventing This on Your Next Piece

Most fit issues trace back to the score itself: an uneven pressure, a stop-and-restart mid-line, or rushing a curve. Slowing down and keeping pressure consistent through the entire score, covered in how to cut curves without breaking the piece, prevents most of these fit problems before they happen.

Where to Start

Beginner patterns with fewer, larger pieces give you more room for small imperfections to not matter visually. Browse the pattern collection for designs built with exactly that forgiveness in mind.
