The most important thing about selecting grains, when you're restoring a piece, like this, lets just say this was a veneered top and say you had a bad piece of veneer, right in here and you wanted to match this up, as closely as possible. Well this is a ribbon mahogany, so you want to go with something that is still a ribbon mahogany and then you want to try to find the color that's pretty close, to being in there. You don't want to go with a flat grain, like this is, even though it's mahogany because that grain will stand out, differently, than the way this ribbon does. Then you've got another kind of mahogany, well that's going to be too red, so you don't want to have that in there and then this is mahogany, which is a little on the dark side, so this is going to be way too dark, to have it in there. You're better off with something that's a ribbon where that color, might better, blend in there. This is a piece of ribbon mahogany too but this color would probably be your closest bet. If you are going to repair an area, let's just say you had a little spot, right in here that needed a veneer, then you're going to want to do something where it's shaped like a triangle and then another triangle. Don't ever just have a triangle and then just come straight across, cover up that bad area and cut a triangle and a triangle, like that. That way, those two long points, it's easier to blend that in, as part of the grain in your finishes if you do it in that kind of manner.
