My first quilt, i didn't thread baste, and noticed that by the time i got to the borders, the corners were wonky a bit. I am always too excited to start the quilting!!!
The 2nd quilt i only basted when it got to the borders, it helped, but there was still too much to ease in. This time i did take the time to baste all of it - so i gotta admit that it's going much better!
So - basting is it for me!!
