I made a shower curtain -- or rather, a curtain that runs on shower curtain hooks - and wanted metal eyelets like purchased fabric shower curtains.
So I bought the kit of 10 eyelets and tool., followed all the insturctions, including the one about hammering forcefully. The problem is that hammering forcefully enough to engage the teeth of the washer means the tool is well inside the eyelet and the "anvil" backer is stuck there too.
After attempting to loosen it with pliers and by prying it with a screwdriver, I gave up and made buttonholes for the remaining holes. I suppose I can leave the metal tool and anvil there as a sculptural accessory, but I really would prefer not to.
