Spoonflower...have I died and gone to Heaven?

Someone from my SAQA visioning group pointed me to Spoonflower, a site where you can send them a design and they will print your fabric. It seems a little expensive, about $18/yard, but when you consider that it costs thousands to commercially print a design, its pretty cheap.

So, now I have to decide: out of my gazillion paintings, drawings and textile designs, what do I start with? Will they put it in repeat right? so there are no "track marks" running up and down the fabric where it repeats? Can they do watercolor effects, color traps or will it be just flat color?

Well, these are a couple old designs I am toying with sending. My question is...how can they do this for only $18 a yard? What kind of equipment do they have? and where can I get some so I can do it myself?

Oh, GRRRRR, got my CMYK and RGB color mixed up. Hopefully the turning square will have the right colors now!
