AC Moore recently opened up in the Pyramid Mall. It is a great store for all kinds of needs. They sell materials for any and all arts and crafts projects that one might want to do with their children.
They also sell great solid color t-shirts to either do crafts on or just to wear. The shirts are extremely cheap and I've actually gotten a couple just to wear, without doing any work on it.
AC Moore has a huge selection of frames and, something that I think sets them apart, is that they have pre-cut mats for most normal sizes. This comes in very handy as the pre-cut mats are much cheaper and just as good as custom ones in most cases.
I would highly recommend AC Moore to anyone in the Ithaca area.
