Have you ever tried to mark template lines on felt? It’s nearly impossible. I don’t know what others do, but I find it easiest to draw the shape I want on freezer paper, adhere the freezer paper to the felt, then cut out the shape with scissors.
Here’s the technique in more detail:
1) Use freezer paper. You’ll find it in the grocery store, near the plastic wrap. It has a shiny side, and a dull side.
2) Draw the shape you want directly on the dull side of the freezer paper. It is easy to see through the freezer paper, in order to trace from a book or pattern.
3) Roughly cut out your shape, removing most of the excess paper around your drawn lines.
4) Use a hot, dry iron to press the shiny side of the freezer paper to the felt. Don’t press hard — only until the paper just sticks lightly.
5) Cut on the line with scissors. Peel off the paper. Done!
(I also use freezer paper for hand applique. I’ll have to tell you about that some other day, because that technique is slightly different.)
Make a simple pin keeper from a piece of felt. Carefully trace a nice, round circle onto your freezer paper. Press it to the felt, cut it out, and you’re done!
This pin keeper works well if you carry your sewing supplies in a hard box. Don’t toss this into a tote bag!
