OK I got a surplus poncho liner that I plan on using as a TQ. My question is, what do you do about a footbox?
I searched the forum but couldn't find anything that addressed this. I don't want to do any cutting because I may try the no sew UQ with the liner. I want to explore both options TQ & UQ before I buy any more liners.

I already have a DIY UQ that I was given and one I made myself. I don't have a TQ.

Thanks for the help.
