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.
Legume hays are much to high in protein for a regular part of the chinchilla's diet. Grass hay is readily available and very inexpensive. Some breeders choose to supplement their chinchillas' diet. If you choose to offer your chinchillas a supplement, feed no more than one teaspoon per day per chinchilla. Ingredients can be found at a local health food store, or at some feed stores. Supplements can also be fed by hand as a treat.
