This year so far Holly and her team have digitized 2,950 designs for the members design library at Artistic ThreadWorks. That's a LOT of digitizing in one year!
Most of them are already in the library and available for download but that number also includes the ones that Robin has scheduled to release through December 31st. There are still a few slots left so we should surpass the 3,000 designs mark for 2007. If you joined the site on January 1st of 2007 ($19.95/quarterly) you would be getting 3,000 designs for $79.80 which works out to 2.6-cents per design just for the new ones. If you add in the archives (previous years designs) then it comes out to $79.80 / 15,000 designs or about a half-a-penny per design.
I don't think you'll find a better (legal) deal than that in the embroidery world.
