I like the backs to look (as far as possible) as nice as the fronts. This is the back of a serged snowball quilt.
I took the picture for a tutorial and the orange marks are there to demonstrate pressing each seam toward the darkest fabric. This back was the nicest I've ever made.
Serging is not an option for many patterns - it adds too much bulk to the seams. But for this snowball quilt, serging works well and, since it's for a toddler, I think it will wear well.
