How many hog rings should I buy?

 

IIRC, you will need right at 100; go ahead and get a second bag, they're cheap.

If you've got a little extra money to spend, you may want to check out the hog ring pliers at The Eastwood Company http://www.eastwoodcompany.com/cgi-bin/sgsh0101.exe
They are spring loaded and have rubber grips. I prefer the angled ones, they spring open; the straight ones spring closed. They will make the job much easier. But if you are on a budget, the JC Whitney ones will do the job.

 

Thanks for the link, I will deffinetely need something to make the job easier. Will just the angled pliers work, or do I need both of them?

 

Unless you plan on re-upolstering for a living, you really only need one pair. The angled ones get into the tight areas much better, but the straight ones are a little better for the open areas.
