And if you didn’t like that the finger on his left hand was pointing at nothing, you could redraw that hand to have a mitten on it.
Then you’d want to print out the image on computer paper and trace it onto parchment paper. (Or if you were smart, you would cut the parchment paper down to size and feed that into your printer so the image printed directly onto the parchment paper.)
The hardest part of the whole project would be figuring out what to cut away from the image (the parts that you wanted to paint black) and what to keep (the parts that you wanted to remain white).
You’d have to cut the silhouette out with a sharp craft knife.
Then you’d want to go back in and carefully cut away all of the inside pieces. (All of the pieces on the left side above are waste. The pieces on the right side are the stencil.)
You’d have to iron your stencil onto a towel. (Parchment paper will stick to fabric when it’s ironed.)
You’d want to mix a little textile medium in with some acrylic paint to prevent the paint from cracking after it dries.
You’d want to pounce the paint onto your stencil.
Then you’d get to the fun/nerve-racking part: peeling away the stencil to reveal the final image.
If you did it right, you would end up with nice crisp lines of black paint on all the edges.
And Santa would be smiling at you.
Then you’d want to run a hot iron over the back of the towel to heat set the paint, and you’d be done.
