We used the 1” charm, which I personally like better than the larger ones, because I am not used to wear bulky charms. That one is big enough to be creative but when wearing it, it doesn’t get in the way ;-)
Here is what we did:

Oh and by the way, If you don’t want to make inserts yourself…. I’ll be glad to do that. You can order the 1 inch charm with 4 inserts for $25. Inserts will vary. All you need to do then is decide which one you want to wear first and get a chain or cord for it… Let me know if you’re interested.
Just a refresher, here is a link to the other sizes of charms I have posted previously! Have a wonderful day...
