My hobby lobby carries the heavy body and the basics in the liquitex brand. I believe my Michael’s is the same. Come to think of it, I don’t think I’ve seen the soft body in stores around me.
Do you have a ■■■■ blick? Looks like they carry it from the looks of their website. Micheals sells it online only and you can always order from liqutex themselves. If you write them for samples, they will send you some.
