I used to frequent Michael's stores for my crafty needs, but now I am hooked on Hobby Lobby. This particular location blew me away because it is big, well-lighted and clean. I have browsed this store for inspiration on a number of craft projects and always managed to walk away with a few real bargains. I've even bought items that have proven handy at work -- you have to get pretty creative sometimes to find the perfect vessel or tool suitable for molecular biology labwork!
Two things to comment on that most people may not realize about Hobby Lobby. One is that if you sign up to their mailing list through their website, they will e-mail you 40% off coupons fairly regularly (applicable to only one item at the store... but that can really add up if you use it wisely). The second thing I want to mention is the framing department. I had recently discovered an old frame that was the right size for mounting a fantastic map I've always wanted to display. I noticed Hobby Lobby was having a special sale on matte artboard and decided this was my chance to finally do it right. So I brought in the map, the frame and worked with their employees to figure out the best strategy for framing. They had the work done quickly (2 days or so) and I only spent $45 for a beautifully custom-framed piece.
The staff here was so friendly and helpful, that this has become my first choice for meeting any of my art and craft-related needs.
