I learned to stencil with cardstock, instead of freezer paper.
I don't have any pictures of the process, I will take some next time I do some stenciling

Print out, or hand draw an image onto 110 Lb cardstock (a heavy weight cardstock)
Using your xacto knife carefully cut out the black part of the stencil.
Be careful about 'islands' - any white parts surrounded by black. Leave part of it connected to the outer part of the stencil.
Once the stencil is completely cut out, spray the back lightly with spray adhesive. Let sit for a few moments.
Line up the stencil on the shirt/pants/fabric and press down, making sure that the edges are sealed to the fabric, otherwise it may bleed under the edge
Follow the directions on your textile medium on how to mix with the acrylic paint. Or use a fabric paint.
Grab your paintbrush and start painting. If you brush from the outside in, it will be less likely to bleed.
Let it sit for a few moments before peeling off the stencil. If you plan to use the stencil again (usually only works without a lot of small details) then work slowly, I use the tip of my xacto knife to help.
Once you've removed the stencil you can go back and fill in anything that looks bare, or where your connections to the islands are.
