You need the Pebaro rhinestone set as well as a kitchen towel and a T-shirt, which should be embellished.
First put a kitchen towel or similar in the t-shirt so that the adhesive for the rivets does not press through to the lower side of the t-shirt.
Select any rivets from the set and lay them out as an individual motif on the shirt.
Select the right picker, screw it on and wait until the piston is really hot. Then attach the rivets vertically from above. Heat each rivet until the adhesive layer has melted and the rivet sticks.
Gradually glue each rivet in place. A t-shirt is ready, which is not available for sale.
Tip: Rhinestones from the set can also be used.
