Trimming Quarter Circles {Video Tutorial}

I like to use oversized concave templates when piecing quarter circle / drunkard’s path blocks. In the short video below, I demonstrate how I trim curves to size so the curves will match nicely when they are sewn together.

Much like oversized HSTs and flying geese, I like to use oversized concave templates to allow me the ability to trim the block square after piecing. The ability to trim my blocks square after piecing has greatly increased my piecing precision.

The bottom line is that it’s all about where the ruler is placed for trimming. The video and graphic above show how I position and trim as a right-handed quilter. The two edges of the convex template should be lined up with the size you want to trim to on your ruler, and the concave fabric should be trimmed away, leaving ¼” of concave fabric remaining at the edges of the curve.

And for all my left-handed friends, the bottom row of the illustration above will be what it looks like for you to trim up the left hand side and then across the top of a ruler.

There are certainly times when more concave fabric is desirable, but when a pattern calls for trimming to leave ¼” of concave fabric, I hope this quick post helps!
