This would be a beautiful front. If you don't like it, you could make it for a charity, or use it as a "picnic" quilt, or donate to a raffle, etc.
When I clicked on this, I thought I would find an example of what I usually do for a back. I use all the scraps leftover from the front, including fabric I bought for it that ended up not being in it. But, I just sew them in the biggest blocks or rows that I can.
