That is pretty amazing for an early attempt. The stitching and that edge are first rate. :thumbup:
I like the stamping but I will comment...it is the Internet after all.
That stamping pattern is a classic and is sure to please just about everybody...you will do that over and over again. However, I notice that you've changed direction of your curved tool down the middle. I know why you did that...because when you get to the edge, you can't keep it up...am I right? You either have to stop short or go over.
Again, everybody loves that pattern and you will want to do it again over and over. So what you want to do is buy at least one more, and probably two more of that same stamp tool and grind the left half off of one and the right half off of the other. That way, you can keep the pattern going like laying bricks all the way across the piece and when you start running short on room, use one of the "halves". If you are kinda fanatical, and based on the very high quality of what you've done, I'll bet you are, you could even create a couple of other tools like one where you grind of 25% of of each edge, 17.5% off of each edge, etc, etc, etc, so that you could keep that pattern going no matter how tight of a space you get into.
I have four, a whole, the two halves, and the one where I ground off the both edges and left the middle.
