These go on easy and stay there.

The leather patches are really nice for making swag for your group. I engraved a handful and presented them to the newly elected officers of our organization. I also surprised my mentor at the woodshop I go to with a patch engraved with the woodshop logo. I haven't tried all the varieties of the patches but the brown ones that engrave to gold and the black ones that engrave to silver gave the best results. But, remember, I am sooo very much a newbie to all of this but I am having sooo much fun. Now, if I can only figure out how to get points for this review, all will be right in my xTool world.
