Read the intro first if you haven’t already.
Download the pattern PDF and print it out on heavy paper or cardstock. It’s designed for US Letter, so printing on A4 will result in a bear that’s just a little smaller but not enough to matter.
Don’t forget that you’ll need two of each leg piece, and four ear pieces.
If you’re sewing the bear from upholstery velvet, I recommend cutting the pattern out without seam allowances (that is, just the shaded areas). Trace around the pattern pieces with an ultra-fine Sharpie or something similar - make sure it doesn’t bleed through the fabric pile. This will be your seam line. Leave enough space around each piece to cut with an adequate seam allowance.
Felt may not seem like it has a right and wrong side, but some felts have slight differences. It doesn’t matter which side you use, but keep it consistent.
The easiest way to cut felt accurately is with freezer paper. Trace your pattern pieces (without seam allowances) onto the non-shiny side of the freezer paper or, if you have an inkjet printer, just print directly onto the paper. Make sure you don’t accidentally print on the shiny side, or you’ll probably have a smeary mess, and definitely don’t run it through a laser - it’ll stick.
Now gently iron the shiny side of the paper down onto your felt. If you’re using 100% wool felt, you can use a higher iron setting; synthetics will need a lower setting. You aren’t trying to permanently fuse it, so it won’t take much. Once that’s done, just cut the pieces out of the paper/felt fusion.
If the backing won’t show it, you can trace the seam line like you would on upholstery velvet, then cut leaving a seam allowance. Otherwise, trace around the whole pattern piece.
When you cut the pieces out, make sure you keep the blade of the scissors that’s on the fur side against the backing fabric. Slide the point between the pile and backing so that you end up with as little loose hair as possible. If it’s a thick pile, shave the seam allowances (either with the scissors held flat to the backing, or with a pet hair trimmer). Be careful you don’t clip any of the pile that isn’t in the seam allowance.
