the super glue may not be as strong as wood glue,,, if it was my bow,, I would use wood glue,,, then I would wrap with sinew,, I think the sinew shrinks more than some backings ,,, having a healing effect on the problem area,,, it wont be too pretty,, so a thin rawhide wrap over the sinew(when dry) can make it look a little better,, if it holds,, it will be fun to shoot and the patch soon forgotten,,,, I have repaired similar and worse issues using sinew,,, I have not tried the linen,,, it may be an option as well,,,I was like you,, I had a hard time giving up on a project,, so went to the bitter end on most,, some success,, some not,, but learned alot about repairs,, which comes in useful if making wood bows,,,
