I like the IKEA Trofast storage system. It's not a low budget solution, but it has made organizing my sewing projects and supplies and breeze, and it makes my sewing room look professional. It's actually marketed in the IKEA children's section, but is perfect for a sewing room. It is a wooden frame with plastic buckets that slide in and out to serve as drawers. There are 3 different size buckets you can choose in a number of colors, and a few different size frames. I find it useful because you can choose your storage size depending on what you want to store in each bucket. Additionally, I find it sturdier than the plastic sliding drawer sets from Rubbermaid.

Years ago I bought an IKEA desk for my sewing room... adjustable height table, large working surface. I am not sure if the model is still around, but IKEA offers great desks ideal for a sewing room.
