I am a VERY new quilter; this is actually my first project.
My oldest Son and his wife are having their first baby. I came across a bedspread that my Mother had made for my son when he was a baby (25 years ago)
I got the bright idea to make a quilt out of it for the baby.
I brought fabric, cut out squares, even got them all sewn together, and it looks very nice (if I may say myself)

Here's my problem, I am stuck on how to do the back. (And I won't even mention the anxiety I have thinking about the border...Baby steps Judy, baby steps!) I bought a really nice flannel so that it would add some "softness".
The quilt is approx. 60 in. I bought 4 yards of the flannel. It, of course is not wide enough. Do I just cut it in half and sew it together?
I hope that doesn't sound as dumb to all of you as it does to me.
I appreciate any help you can give me.
THANK YOU!!
