Question about edges of pre-cuts
I've made a few things with pre-cuts (a duvet cover and a wall hanging) and I'm frustrated with the zig-zag edges. Where the heck is the edge of the fabric? Is it at the bottom of the zig-zag (A) or is it at the top of the zig zag (B)? See pic below for A and B. The zig-zag is about 1/16 to 1/8 of an inch and it makes a difference in achieving the correct sized squares according to patterns. Thanks in advance for the clarification!
