It ended up being really easy, and significantly cheaper than buying them. So, I figured I'd share with you how to make them.
I bought a pack of ceramic magnets from Michael's and used a coupon to get the pack of 4 pairs for about $2. Then I pulled out my vacuum sealer and a small piece of vacuum bag material.
There you have it. I told you it was simple! Plus, for only a fraction of the pricey store bought ones. From here on, it depends on the pattern how the magnets are sewn in.
