I know what you mean. Was in the same predicament for months for a quilt for my little grandson. Bought fabrics as I saw them on sale - too many by far. And finally settled on just a few of the fabrics, knowing what my little guy liked, and found a simple pattern in a book called Bundles of Fun by Karen Snyder, that I happen to have. It's turning out really cute. Am all finished with top and backing but have to go get some batting tomorrow to continue.
But it took a lot, repeat, a lot of mulling over the fabrics and patterns before I could decide. So, keep mulling and something will come to you. Good luck!
