Making the rope was.....interesting.

1. I started with 1/8" thick boards of maple and rosewood from the hobby store. They were 3" X 24" to start with. One board of each was enough to do the body and fret board.
2. I tilted the table saw blade to 45deg and ripped lenthwise about 3/8th wide stips
3. Then glue the strips up m/r/m/r and plane the new board smooth. Make sure you don't have the same color strip on both sides or the pieces won't match (start on maple, end on rosewood)
4. Then cut that board at 45deg cross-wise about 1/4" wide.
Now you have strips of binding 1/8th thick by 1/4" tall with 3/8" sections. My strips were ~4" long but it depends how wide your glued up board is. You can glue them end to end to make a long strip or use them separately. (I broke a lot of strips in the table saw)
I installed each 4" strip separately. I used a clothes iron to heat up each strip and bent it right on the uke body, then glued and taped. I think its easier to work with short strips. Just lay a strip on the workbench and drop the hot iron on top of it and wait 20sec or so. Then butt it up to the previous strip and bend around the body.
