How do u thread a string through a grommet when the shoulder is blocking the grommet. It is a shared grommet btw. Forgot to check where the shared holes are :S
If you don't have a good awl or a string puller, you can also cut the end of the string with a sharp angle, and try to push the trimmed string end through the grommet with a needle nose plier. This works most of the time. Or you can using some dental floss, this method has yet to fail me
you mean the grommet is blocked by the side support? those can be tricky at the best of times, if you can't get a pair of long nose pliers in there you could try a string mover on themain string (inside the frame) to try and make the path through the grommet a little clearer. failing that you're into dental floss or the guitar srring method...
