Welcome to the best little site on the 'net, Nicholle!
I would suggest also that you check yard sales for old cotton shirts that are able to be cut into squares for very little money. There are lots of churches and church groups that have 'gently used' shops, I was able to build my stash for very little cash a couple of years ago when I was a tad broke, course I keep myself broke adding things to the stash! Good luck on the hunt for items to use in your quilt top.
