Spendlove has graciously made one that is currently free at My Garden Embroidery...if you have not tried a zip bag yet...this is the perfect place to start!
Oh, I'm looking for a site that sells just the zippers. Love the mygarden site!
kreative kiwi has nice ones plus you get a design of equal value with your purchase, look under in the hoop designs
Hmmm, Kreative Kiwi does not mention they are finished inside with no raw edges...so I am not sure that they are...if that is important to you, I would ask before purchasing just to be sure...
they are, I have some of them, this comment is from the site-
The Bag/Case is made completely in-the-hoop, including machine neatened seams, so no raw edges.
Ah, that's the key..."Machine Neatened Seams"... I do not think that this is the same as some others that are totally finished off on the inside with a finished seam inside...I think that is a big difference...at least for me...
