There are quite a lot of clay pots (with a reddish clay) that I've seen made. Possibly you can work something around this, with painting the pots. They look quite nice after they're painted. I have not seen the firing process but it seems to be quite rough work. I really like the pots however.
Some years ago in the US, we bought a very small pottery set (I think at toys'rus) for our daughter. The red pots that they make here reminded me a lot of this small pottery set. Anyway, I don't think you can go wrong with a 'pottery' class. There are certainly about 20 of these small 'factories' on the way between Santiago and Santo Domingo.
Also, something that I've seen here are very rough baskets made of twigs - when the twigs are still pliable, the baskets are woven. I miss good craft in the DR, yet, over Chrismas, the animals and nativity scenes made of hay, are quite attractive. A bunch of hay, some chicken wire, someone with a creative eye for nativity scenes and hey presto, you have a Chrismas decoration.
Possibly these ideas may be helpful to you.
