I also recommend backing paper. All stencils (including existing ones) can be filed neatly and dust-free. 
You can also find this here in the shop.
 
Delicate stencils like these lose their adhesive strength more quickly than stencils with large, continuous surfaces.
 
 
The self-adhesive stencils can be used multiple times. Carefully rinse off any paper and paint residue under running water. Always stick it back onto the carrier film and store it away from dust. Under no circumstances treat with heat (hot air dryer). Protect from sun rays and heat.
 
The self-adhesive stencils are designed and manufactured in every detail by Schlichtbunt.
