I was going to whip the edge with the strips I used in the border but they were shredding too bad so I did a binding much like a quilt binding. It worked out really well. I saw Debra Inglis using that technique on her Laszlo. There are good directions for this method in Cynthia Norwood's book Primitive Hooked Rugs for the 21st Century. If you like primitive you really should take a look at her book. It is a wealth of information.
As simple as the design is, anytime anyone has seen it I got a WOW! It has a lot of impact. This is, without question, one of my top favorite rugs.
