How to do it
Draw the shapes onto felt using the template and cut out.
Turn the decoupage paper design upside down and turn the vliesofix with the adhesive side down towards the decoupage paper. Fix the vliesofix onto the decoupage paper with an iron.
Trim the excess vliesofix.
Separate the paper and the vliesofix.
Now fix the decoupage design onto the felt shape with a piece of grease proof paper between the iron and the decoupage design.
