I drew the Chain Link out in EQ as a 7 inch block and then printed the rotary cutting instructions as a 10 inch block. There are a lot of very tight cutting instructions into the 16ths.
I believe we can make this block by fattening up our 1/4" seams. We only need to lose 1/2 inch per side. There are 4 seams per side. My math says we need to make our seams about 3/8" within the block to take up the extra. That's 4 x 1/8 inch = 4/8 = 1/2 inch. The outside edge would have a bit more fabric on it. It would 1/4 inch per side. Does this look doable?
