I feel so lost. Reading most of the above almost seemed like trying to read Greek. (I'm a hands on girl..and need to do it over and over to actually learn it.)
I've only made two quilts and I did the same 3 inch binding on both. The fabric store calculated how much fabric I would need for binding, but I wanted to know how to do it myself. For the two quilts I've already done, I cut three inch strips and sewed them together on a diagonal then pressed in half before sewing onto the quilt and then folding over and doing a blind stitch (?) to hand stitch it on. I found a tutorial on youtube on how to connect it diagonal at the ends.
I will measure my blanket to see what I come up with.
