I'm about to sew waistbands onto the two pairs of jeans I've just made, and that means sewing eight hooks and forty eyes.
The forty eyes wouldn't be so tedious were it not that all the time I'm working, I know that even though I use filament-polyester upholstery thread, and I'm careful to buttonhole tightly and never use so many core threads that the eye has to be forced into the hook, and I inspect the hooks for rough spots, the steel hooks are going to chew through the eyes.
At one time, when you bought hooks, in addition to the loops that come with then now, there was for each hook a metal eye -- where the loops look like the letter omega, the eyes look like the letter I, with loops at each end instead of serifs. This made a very long-wearing substitute for a buttonholed bar tack.
Are these maybe still available somewhere on the Web? I'd prefer to buy them separately, since I need five eyes for every hook and already have a pound of #3 hooks, but I'll buy a hook and a loop for every eye if I have to.
