A4 Size DIY Craft Mandala Stencil for Painting Scrapbooking Stamping Stamp Album Paper Card Stencil Template, Pack of 9

What’s the best way to clean the Stencil?

How large is the stencil it self? Will they fit on an 8x10 canvas?

Can i lay it across a curved surface and it hold true. Like a motorcycle fender. If i tape it down will it stay molded or will it resist and make it?

Are these 9 individual sheets of 8.3"×11.7" or one sheet with all 9 designs on them?
