You said some of the triangles and the corners weren't the same size, because of lack of fabric. If anyone says anything, especially since it is for your nephew who is a map maker, just tell them those are small islands, like ones someone finds on a map, because there wasn't enough land to be a large continent. But I'll bet noone but will notice or know that they are done that way. Just a completely beautiful piece of work. I am sure he wil just love it. If he doesn't my son majored in Geography and would love that. lol. It is beautiful.
