No sew hooks

[madness-begins.livejournal.com]

I have a skirt that uses hook and eyes, but I only need one hook, so I bought a package of four. I gained some weight since the garment was made and I can make it fit properly if I install another hook.

My question is, how do I fasten the hook to the skirt if it's a no sew hook, and do they hold up well?
