Hey Ladies happy days to you
Sandy it makes it super hard on the next guy if your round is not exact. If we all use blocks we know they come in standard sizes and it reduces what can be done if its not right. Your round should measure 4.5 or 6.5 depending on where you are on the round (first round 4.5, second 6.5, thired 4.5 and so on) before you sew it on. Once you sew it on it will show 4.25 til the next person adds their round and it is a 4" finished quilted round
confusing but trust me if everyone was off a bit it would some pretty creative or very very simple rounds (strip, then strip, oh maybe two strips) because no one could come up with an even pattern. Hope that helps. Glad you are figuring it out. My first one the center was off .25 and I know Jaba has had to cover for someones half inch before making her round .. hard to do. so its just a courtesy for the group to follow the set sizes. We all want this to be FUN in the quilting room!
