Fabric Advice (Help me spend money ;p)

Has anybody used the combed cotton lawn from Dharma Trading? Or the cotton lawn from Silk Connection? I'm looking to make some whitework embroidered engageantes and want something that is very sheer and light. A lot of things I've read say "muslin sleeve ruffles" and talk about using lawn. I am going to be working this weekend and will have a little extra cash to spare, so I'm looking for help in spending it. :) (After all, I should only need a yard.) Looking for something like this. Any advice? Any other fabric suggestions for this? (Preferably nothing too pricey, and hopefully shipping doesn't cost an arm and a leg either.) Thanks!

Oh also, finished binding the top of the green stays. Woot!
