i have a design wall that's made out of homasote. it reaches all the way to the ceiling and is 12' wide. i can hang a whole quilt from it (a little bit drapes on the floor). BUT ..... everything has to be held in place by pushpins. so when i do blocks and want to see an arrangement or even bits of blocks those pins get to be a nuisance.
i want to turn it into a .... different board, that i can slap blocks against and they stay there. i went to my lqs and tried white flannel. i let it drape over the edge of the counter and the lady pressed some fabric pieces against it. they rolled right off. same with felt.
what are you all using? it has to hang straight up and down, not angled. i will simply cover the homasote with the ...... stuff and staple at the ends.
