I have gotten a few e-mails from some people saying their trees did not loose their color. They got lighter but not white. Well I was talking with Angie she was told me on her doll-loop they have talked about the fact that once bleach is opened it looses it's strength. So if your bleach is old, that might be the problem. When I get a chance (not till probably after Christmas). I am going to buy a new bottle of bleach and try using that and see what happens. If you have done any trees I would love feed back on your trees and if your bleach is old or new.
PS. Check out Angie's wonderful spice tree. I am going to see it today and can not wait !!!!!
