What's this THINGUMMY WHATSIT called in needle felting?

[LaurieFairyCake]

The backing thingy that you felt the wool onto - to make the picture?

After making one at a craft event yesterday I'm obsessed and went out of my way earlier to go to the shop that ran the event and they're shut

I don't know but @catmint is a fabulous needlefelter and she may be able to help you. Hopefully she's got her @ thingy turned on.
