My shoulder was funky so I switched away from my main craft of beadwork to doing Crochet for a while. I decided to give Tapestry Crochet a try after coming across this great pattern for a bag with Celtic knotwork designs, from Etsy shop penelopescrochet. After years of trying to find offset brick graphed designs for peyote stitch that I like, it's nice to be able to work with nice square grid patterns. Cross stitch, needlepoint, loom beadwork and even pixel art are good sources. A great design can be used in many crafts.
Now there are a couple of nice sites for grid or bead graphs from pictures you feed them:
