Houey Hong is a training center where young women can learn weaving, dying, and sewing which provides them with good job opportunities, and can enable them to start a small business at home. The quality of the training and resulting products is excellent.
You can visit Houey Hong in passing if you're in the area (unlikely!), but i would recommend taking a half-day or full-day class in either weaving or dying. It's a lot of fun and teaches you respect for the women who spend days on end working on a loom!
The center is gorgeous, surrounded by trees, in a quiet area with little fish ponds, shade, the occasional goat, and the sound of cicadas. A beautiful way to spend a day with friends.
