I think I wouldn't even want to walk in the door with out a list. You can find things in the on line catalog or you can go on line and "join" and they will send you a catalog - it took a while to get a catalog but we did get one. That light is really nice - I found mine in two locations in the store. We also bought a light that hangs on the wall - we like them both.
http://www.ikea.com/us/en/catalog/products/20169658/ you can search IKEA and what ever item you are looking for. It pays to shop on line ahead of time - they do have people who will help you find things. There are a lot of impulse buy items. I think you might also like to look up "IKEA hacks" and "IKEA hacker" on line for some really great ideas what to do with IKEA stuff. Some people even 'hack' the IKEA bags. You can also search on line for IKEA sewing room ideas and then hit images.
