Is the clear adhesive vellum sold at Michael's actually as clear as a transparency or is it actually white? We used an adhesive vellum at a make-it-take-it at Michael's a few months ago and it was more whitish than transparent. So just wondering if there are 2 different vellums that are adhesive. I'm looking to print a poem on a clear overlay and place it over an entire photo without using embellishments to hold it down. A self adhesive one sounds good to me.
