Jenniky - I know that I'm not doin' my QAYG right now. I do have an idea about your hypothetical question. If I had different sized blocks that it wouldn't change the pattern ta cut 'em down (& they are already quilted) I would
1. Decide where I wanted 'em cut down, kinda like fussy cuttin', & draw that onto the block,
2. Then before I cut it out,I would sew a 1/8" inside that line, ta stabilize it,
3. Then I would cut it out.
This would seam would be inside the seam allowance & would help ta keep the quilted lines from unraveling.
