Heat N Bond is an iron-on double-sided adhesive used for applique. We use it a lot to add lettering to bunting.
Trace your design onto the paper side and cut it out roughly. Iron it onto the back of your chosen fabric, cut it to the traced line, peel off the paper then place it onto your background fabric and put the iron on again. The iron will only ever have to go on for a few seconds.
Heat N Bond is the same sort of thing as Bondaweb but we have found it to be much better.
Sold by the half or full metre. 17" / 43cm wide.
