I've used this tape it is Wonderful! but I think expensive.(my opinion)
It is called "HEAT PRESS batting together" and includes 10 yards of fusible 1 1/2" wide cloth tape. Their email is : www.heatpressbattingtogether.com or they also have number on their bag. The one I bought was from a LQS and paid $8.99 for it.
