Re: [BKARTS] bookboard showng through pale bookcloth



Thanks, Nancy.  Your information was very informative.  I was actually
asking Bev about the adhesive that she used on the bookcloth that she made
herself using the fusible webbing.  I have read that some use the fusible
web to bond the paper to the cloth, and then use an iron to bond the other
side of the webbing to the bookboard.

Thanks,
Ann
