I get most of my computerized designs at Munnich Designs. Think I have all of them up to this date. Also like the designs found at Intelligent Quilting and One Song. I don't download all the freebies I find though, only the ones I think I might use in the future. Don't want to clog up my computer with more than I can use.

Emboidery library she has good designs and runs sales and specials, there are also free ones to download each month.

Designs by Deb is also a good one, currently having a sale as well.

urban threads--lots of contemporary things, lots of traditional ones. holiday designs, baby stuff, "beer" designs, dragons, skulls. different, fun.
