I finally bit the bullet & risked the traffic for a trip to Joann's. I bought backing & binding to complete the 2nd t shirt quilt. I only bought the required amount according to the quilting calculator. There was more than 1 yard left on the bolt so the woman cutting said she couldn't call the remainder a remnant. I was tempted to buy another 1/3 yard so I could have the rest as a remnant, but I was strong! I resisted the temptation. Since I plan to move in the next few months, I don't want any more stuff I have to take with me. So 4 2/3 yard for backing & 1/2 yard for binding. All should be used & not added to stash.
