This is how the window pictures are created:
Step 1: Prepare the napkin motifs
Firstly, you should separate the desired motifs from your napkins. It is best to carefully tear the napkin apart to separate the top, printed layer from the lower, unprinted layers. Only the printed layer will be used.
Step 2: Coat the fabric with napkin varnish
Take the fabric you want to embellish and apply a thin coat of napkin varnish to it. Napkin varnish is a special adhesive that ensures that the napkin adheres to the fabric and is sealed at the same time. Make sure to apply the varnish evenly and thinly.
Step 3: Apply the napkin motif
Now carefully place the top, printed layer of the napkin motif on the fabric. Once the motif is well positioned, apply another thin coat of napkin varnish. Do this carefully to avoid folding stars and bubbles. Then leave the whole thing to dry thoroughly.
