I went to a free demonstration they had on Worbla and similar products for making costumes. I really enjoyed learning about the material and it was presented very naturally by someone who had been working with the material for a long time. I took a quick walk around the store after the lecture and found a lot of great items for garment and costume construction. If you're looking for a central location to get your supplies this may be a good option.
