Verging on the greatest thing since sliced bread, this grommet kit was exactly what I was looking for to put the finishing touch on a handcrafted gift for my husband's birthday. The directions for use are on the back of the packaging and if you use the included diagram (with parts labeled A, B, C...) you'll quickly be on your way to installing 1/4" (hole size) grommets. The only thing this kit doesn't have is a hammer, and you'll need that before you get started.
