alternatives to baize backing on coasters

[smiley_mug]

I'm struggling to get hold of the 90 mm baize backing from bMS and I wondered if there are any alternatives. I know someone that sells the coasters without any backing at all just their branding sticker on the back but I'd feel bad doing this. Although the cost saving would mean I could possibly wholesale them. I've heard the cork backed coasters have crumbling/quality issues. Any advice?
