Before I started printing on fabric, I needed a surface to which I could pin fabric to hold it taunt while was I stamping, rolling, scrapping or screen printing. I made print boards from 1" insulation board that I purchased a hardware store. I layered a piece of leftover batting and drop cloth material on top. Both were duct taped to the insulation board to hold it secure. I like the drop cloth material that I found in the paint isle of the hardware store because it absorbs moisture and paint/thicken dyes doesn't smear onto clean cloth. However, duck/twill material or a plastic drop cloth can be substituted. The insulation board comes in large pieces and can easily be cut down with a utility knife. Two points I recommend thinking about when deciding what size to make your print boards... First, what size fabric to you want to have? Yard pieces, fat quarters or something else. It is much easier to have the board be the "right" size then to have to re-pin. Second, how big of a space do you have to work in? and where will you store the boards when they aren't being used? Having big boards when working on half a table can be an accident waiting to happen.
Good luck and Happy Printing!
I love using leader/ enders when I am chain piecing. It was an idea from Bonnie Hunter. Instead of using a scrap piece of material in between chains, use two small blocks. You can work on two project projects at once! I keep a pile of 2" scrap squares next to my machine for this reason...Happy piecing!
