Ok, here I just finished the top for a tree skirt that is 47" x 47", and trying the like of me to figure out how 1 and 3/4 of a yard is gonna work for this, (this is what the pattern states). It is cut out at a 45 degree angle on the 4 sides. So I went to quilt shop today, and she said it would take 50" x 2 and I still have to piece it. Only a few inches on the side, so would you just cross cut it in the middle sew it up the middle and then trim the sides to correspond with the top, or is there a better way? I ended up with 2 3/4 yard of fabric, though I know I will have some left over. But would there been a better move on my thinking? Less fabric (as I thought it got a little spendy for a tree skirt). Also do you put a lot of thought into the backing? What do you do for yours backs?
