Okay I've had a few people wonder where you can get a tutorial for attaching dome snaps using the hammer method, so I thought I'd made a tutorial for it and share my wealth of knowledge!!! This method is an alternative (an inexpensive one!) to buying those hand plier snap deals. Sometimes they don't work as they should. I'm all for using a little elbow grease and getting the job done right!
We'll start with pics of what you need, and what part goes with what:
I use both snap trays, the package won't come with both. The one on the left has a small knob on it, it's good for positioning the under snap. If you don't have one of those, just put it right on the floor, but hammer gently. The tray on the right is good for the dome snaps. See, the problem I've had is, if I use the one on the left for the dome (it has a concave part on the other side), sometimes hammering too hard on the knob side pushes it through, so when you use the dome side, it dents the dome. You for sure have to use the dome one either way, otherwise it will warp it.
This is how you make holes and what they look like after. Make sure you are hammering on a hard surface and you don't care about the floor (ie concrete basement floor, sidewalk, scrap wood, etc.) This hole punch, no matter how soft you hammer it, WILL go through your floor. So don't use on a good table or linoleum floor, etc.
Put the dome in the concave tray. Place the hole of the fabric over the post on the dome.
Put the underside of the dome snap in place, and using your tool (I like the one on the far right best, the other two are more for eyelets) hammer with medium force 5-6 times. Check to make sure that the post has bent around completely and that the snap is secure.
Repeat the same steps for the bottom snap, making sure to use the tray with the knob, or just straight on your hard surface.
Hammer as above.
Viola! You should have both sides of your snap firmly in place! Try snapping it together. If it doesn't go, it's because one of the posts you hammered didn't get bent into place all the way, so it's touching the other side. Just reset the snap on whichever tray it needs and hammer a couple more times.
Some advice on snaps: These snaps are really strong, and can therefore tear your fabric if it's too thin. Do a test on scrap fabric first if you're not sure. I like to interface anything I'm putting a snap on, it just makes it more stable. Denim and other heavyweight materials won't need interfacing, the snaps work well on just one layer even!
I hope this helps all you Craftsters out there! If anyone has any questions about this, please PM or post, I'll get back to you asap and help as much as I can!
