For a while we have used a heavy duty stapler that we have here at the shop to try to staple chenille stems tot he back of signs for hanging on a wreath. This has worked sometimes, but more often than not.....not.
Then last week we took a trip to the local seed/feed store and browsed through the tools. We had watched Nick's Seasonal Decor use an Arrow Stapler on a Facebook live so we went in search of one.
This is what we found at Moore's Feed Store in Pontotoc and I'm sure you can find them in many places, or on Amazon. We're providing our Amazon link for it.

This tool will be one well worth investing in, if you make a lot of wreaths and need to attach signs. So many if all the signs only come with one hanger on the back and typically you need to attach in 2-4 places to secure the piece well. Just use caution in the size of staples. We used 1.4" staple, anything larger than this might go through your sign. Just keep that in mind before you start using.

For the sign we were using at the time, we folded a chenille stem in half and just stapled over the folded end a couple of times.
