If grandma's creative brain exploded on a Sunday afternoon, this is what it would look like.  They have paints, glues for any surface or material, brushes, picture frames all shapes and sizes, seasonal arts and crafts, beads and bedazzlers, candles galore, styrofoam in weird shapes and blocks, construction paper, wood shelving that you can stain or color any way you like, fake flowers, glass containers, etc.  Also, if you're into scrap-booking Michael's is probably a dream come true.
