They make beautiful quilts. I collected them for several years just for that purpose. You could either use only chenille squares (may need to collect a few more cutter chenilles off of ebay first to add to them) or alternate the chenille squares with cotton squares. I made a pretty shabby chic one for my granddaughter by using different chenille square and alternating with floral ones. Very cozy. Would love to see a pic your chenille.
Also, if it has any fringe around it, you could make a matching pillow and trim with the fringe.
