This setup works really well. If you look around at the local home improvement stores (or Walmart), you can find the items you need fairly easily....even the foam she uses.
I used it on a 5x7 hoop to do 20 jackets (80 hoopings...the jackets zipped apart for warmer weather...put EMS logo on one side, person's name on the other...so 4 hoopings per jacket)...had no issues...sure saves a lot of time overall.
