PVC UC/IC = you see what I see! In my early classes students had to walk back and forth from my machine to theirs after each step of the lesson - VERY tiresome! Someone reminded me recently that I used to say, "Be careful as you walk back to your machine - there is a hole in the floor and what you just saw will fall in before you can try this for yourself!" The big TV screen at the Bernina OKC store allows students to see everything that I am doing at the sewing machine while staying in their seats.
I had son paint this one to match my Bernina 1630 - so vain! I know!
I have another one that I use for closeups when I am teaching tatting on my YouTube channel: ginabea1630
