This listing is for a two pack of the glue refill sticks for the Sewline glue pen. The glue pen is shown here for your reference, it is purchased separately.
It is a water-soluble blue glue that dries clear. It is a quick, convenient way to hold fabrics for sewing. Great for quilting and applique work but also for hemming and general sewing.
Once glued, the fabric pieces can be pulled apart, so not to worry if they are misplaced or need to be adjusted. Wonderful time saver for English Paper Piecing.
