I am going to be trying a mini bow tuck today as a gift for my niece but I have a couple questions. 1. On average, how long did it take to complete the bag, large or mini. 2. I should know the answer to this...but when it says width of fabric, is that selvage to selvage? I'm trying to use my stash and I have a few yards of fabric to use...and so I always forget what the actual measurements are of a yard...so that's question #3...what is the actual measurement of a yard...silly questions, I know...but I won't know unless I ask, right??
