A couple good friends of mine own a coffee house and roastery. They're starting to have a table at our local farmers market every weekend and want to print a sign for their booth on burlap coffee bean bags. I know this can be done...there is already printing on the bags from the farmers and distributors, etc. Has anyone printed on burlap? I'm thinking water based ink would probably be better than plastisol...water based would really soak in to the fibers. Low mesh count? 110? 86? Any other suggestions or bits of wisdom?
