Thank you Marvin and Cindy for your very helpful
responses. I like the idea of using wire, cardboard
pieces, etc. to make details. I think maybe drying
them slower would help. I really appreciate your
advice and I will try that. I am also going to order
some Amaco clay for next year.
I just want to also say that I usually buy Crayola for
most of my products, they are usually a very great
brand. That's why I was surprised with my problems.
It is possible we were using too much water or not
drying it slowly enough. I called the Crayola company
and they were very helpful and gave me some coupons to
make up for the problems I was having. I asked if
other people were having the problems and she said no,
so it also might have been a bad batch.
