Be-stitched is one of the largest tatting stores online. They have over 50 books, more than 100 thread options, simple and fancy shuttles, tatting needles and more! There have been over 100 new items added between June and July.
Nancy and her team go to great lengths to provide great customer service. If you don't see something at their store, just let them know - they'll do their best to get it for you.
They have a monthly newsletter that offers coupons, free patterns, and other great content. And one neat thing I noticed is they have gift certificates... that never expire! Their gift certificate denominations range from $5.00 up to $100. You can get more info on this sweet deal here.
Be-stitched also offers a list of tatting teachers around the world. This is to help those who wish to learn, a chance to find a teacher in their area. This list is quite extensive. You can view all the available teachers here.
