For the bunny shown below, I sewed two 12" pieces of chenille, marked my bunny pattern on the back, cut and sewed them together.
After your piece has been sewn together, stuffed and hand stitched closed, simply throw your piece in the washing machine with a couple of large towels. Toss them in the dryer. Once dried, the chenille will become fuzzy. The more you wash and dry the fuzzier and softer it will become.
As you can see in the following picture, you are not limited to simply sewing diagonal lines. Experiment with any design.
You can also "chenille" pre-printed fabric. Just make sure you layer each panel directly on top of each other. The last layer should be face down and the three layers face up. As you can see, the design, once cut, maintains its original pattern. You can do this for rugs, placemats, table runners, baby blankets,
etc. Use your imagination.
