I'm so glad you like it - and that you noticed the design on the tiny canoe (your eyes must be doing well these days ) I like to see how fine I can get the detail, and it amuses me to add something that might be too small to be noticed at first look. Thanks! I use a scribe from an old drafting kit, but anything with a sharp point will work. It just has to scratch the surface enough to hold ink. You can use a sewing needle. I also use those, held by a pin vise for easier handling. I look forward to seeing what you come up with.
