|Anyone who puts in a lot of snaps will no doubt want a snap-setting tool, but here's how to put them in if you don't have the tool. I just noticed that the directions on the back of the Dritz package are woefully skimpy.
You need a firm surace with padding (washcloth on a table), a hammer, a pencil with a good eraser, a spool (the small Coats brand works for me), and some chalk.
Mark your installation points as you would buttons and buttonholes. Make sure that you understand which of the four parts of the snap goes where:
1-- Decorative part with prongs, right side of the fabric, on top of the placket or opening (where the buttonholes would be)
2 --Flat circle with a ring, underneath the decorative part
3-- Circle with the stud, right side of the fabric on the underside of the placket (where the button would be)
4 -- Open circle with prongs, underneath the stud part -- next to the skin.
Begin with the underside, non-decorative part of the snap.
Place the prongs, sharp points up, on a firm surface, lay the fabric on it and use the pencil eraser to firmly and smoothly push the prongs completely through the fabric. Center the studded circle over the prongs, making sure you get ALL the prongs into the groove. Hold the spool on top of this, with the little stud in the center hole, and hammer firmly. Check for tightness -- if you can get get a thumbnail in between the snap and the fabric, hammer again!
When all the studded halves are installed, put chalk on the studs. Very carefully, press the other side of the opening over them to chalk-mark where the other half of the snap goes.
Install the decorative part the same way. If you are using a pearl snap, the padded surface is very important -- that pretty surface can crack!
I hope this makes sense.
