If you are quilting for a labor of love that is one thing. If you want to make money see what you do as a business. What seems to be missing with the quilters are business skills. I have looked at businesses such as, The Quilt Cafe, price range for quilts $125-$703.
Chinchillas do not need extravagant plants, treats, whatever added to their diet. The more simple the diet, the better. Pellets, hay, and fresh water is all they need. Wheat grass is the only type of live plant I would give my chin.
A chinchilla should be given the best, freshest hay available to you. We feed timothy hay everyday. A handful per animal is a good quanitity to give provided that the chin eats it all. Loose hay can get very messy if you feed too much at a time.
