I love square quilts and smaller quilts because I like to cuddle up with them. Even a twin size quilt is difficult to handle size wise when I'm trying to curl up and snuggle under a quilt on a chilly evening. What quilts I use on the bed are extra layers added at bed time if it is especially chilly and they don't have to cover the whole bed or fall over the edges for that matter. A quilt can be any size you want it to be just by adding or subtracting rows and columns, the size of the borders and such. If experimenting and creating isn't your thing then find patterns that are the size you want it to be.
