Eric...
Made some golden-orange stain and some dark brown stain from dye and methanol.
Stained the whole bow the golden-orange color.
For the wider stripes of brown I used a strip of t-shirt material about 1/4" wide. Dipped it in the stain, blotted it off on paper towels, pulled the strip tight and did about four stripes..dip, blot and repeat. Took a little trial and error to figure out how much stain was needed to color it but not run too far.
The smaller lines were done the same way but with a piece of thread.
Took a while...lol
