I've never made a string quilt, it's on my to-do list and I plan on using cheapo muslin since I have a bolt that I use for garment mock-ups, I know how to build the blocks but when you're putting the blocks together to make a flimsy
1: are you still using the standard 1/4" seam allowance
2: are you pressing seams to the side or open
3: is it possible to use selvages in a string block, I have tons of selvage edges
