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.
You can give chinchillas fruits and vegetables as treats, but these should not exceed 10% of their daily food intake. They are natural foragers so it is suggested that they are given a coarse mix. Be careful not to over feed or they will only eat the good stuff..
