The project takes about 9 hours to carve using a 1/16" fishtail tool. This could be shortened if you’re willing to do a tool change and only use the 1/16 (or smaller) tool for the nametag slot.
After removing the carved nametag holders, we found it was quick and easy to use a file to take care of any sharp burrs and then to use a fabric softener sheet to get rid of any fuzzy leftover material on the nametag holders.
Using adhesive velcro dots we attatched the nametag holders to the students’ desk. Done!
Optionally you could laminate the nametag. It makes them hold up longer, especially if you’ll be moving the nametags between holders in your classroom.
