I think three out of that group of web sites sold to one owner. At one time there were three sites which gave out designs throughout the day and now sweetembroidery.com is the only one that I know of which is giving out daily sets and hourly singles from the older sets. There may be more out there, but the only one I check is sweetembroidery.com. I think embroideryfreefree and freejacky are still operating, but I haven't checked on them for quite awhile.
Yes - that is what worries me about some of those sort of sites - if you were to take out a subscription. Love this site though it has been around for years.
