I actually did it quite extensively for about 10 years, but gave it up about 3 years ago. (In fact, I did a x-stitch for each member of my wedding party and for my Mom and Dad as a gift when I got married.) I have a large, almost finished item I got aggravated with. I even have the framing and matting for it already. It was to be a gift, but when I ran into trouble I just put it away. Haven't done much x-stitching since. But I've been tempted to pick it up again. It would be a great thing to do while waiting for DD at swim practice (hard to scrapbook at the pool, I've tried!). I find that my favorite patterns have come from magazines. I don't usually care for the "kits", as I already have HUNDREDS of the DMC floss colors already. I'd rather buy everything separately.
If you are looking for anything specific, let me know and I will see if I have anything....P
