Usually when I make a baby quilt, I try to keep it around 42" wide. That way a single width of fabric is wide enough for the back. This quilt is 48" wide so I had to piece together a backing.
Here is a close up of the backing fabric. The green one has numbers and the pink one has letters...just right for a pre-schooler...plus lots of animals to look at!
Now all I need to do is finish whip stitching some batting pieces together and I will be ready to pin baste it for quilting.
I could zig zag these batting pieces on the machine but sometimes I get a bumpy ridge when I do it that way. Sewing them this way is pretty quick, anyway.
