Thanks Halitech and YinTx. I appreciate the kind words. That damn triweave is my bane! I love the look when it's done well, but you're right about getting off in a few spots. I used the medium size Craftool, which seems to be easier to keep on line than the small one. One of these days I am going to splurge on one of Barry King's, but for now I can't justify the expense.
To critique myself, I wish I had not used the serpentine in the very corner. I prefer the look of a solid "spade" shape in the corner, but I got in a hurry and put the stamp in one corner without thinking it through, so I had to do it in all four corners. Oh well, another learning experience.
