I started out using regular paper for printing in my printer. Then switched to tracing paper for hand drawn patterns for PP. Now I only use freezer paper, which I can send thru my printer one page at a time. I order it from
www.cjenkinscompany.com. It comes 50 sheets/package. Since I can use one pattern multiple times (up to 7 or 8), I usually need to only print one copy. Cut off extra paper around the pattern, leaving 3/8 - 1/2" beyond the outer edge of the block. I fold back each line on the pattern, over a postcard, before I do anything else. Then iron the pattern a couple times to my pressing surface. This lets some lint and small threads stick to the back, which is what you want. It makes the freezer paper to not adhere so hard to the fabric of your block. Pressing it will not take away your fold lines, they will still be there. Then iron your first piece of fabric , with the wrong side to the freezer paper to your pattern. I lay the fabric down, wrong side up, fold back the pattern on the first line, lay the pattern on the fabric so the folded line is parallel with the grain line, open out the paper and press the #1 section to the fabric. Take it back to your cutting mat, fold back the pattern on the first line between shapes #1 & 2 and trim off the seam allowance, leaving 1/4 or 1/8" sticking out beyond the fold. Using an Add-A-Quarter or Add-An-Eighth ruler is very helpful for this step. Then line up your next fabric underneath w/ raw edges even, sew right next to the folded back freezer paper, with the needle going in right next to the fold. Iron once to set the seam, being careful to not hit the shiny side w/ your iron. Open the fabric at the seam and press again on the right side to open out that seam and adhere the new fabric section to the freezer paper. Fold back on the next sewing line, trim seam allowance, add next fabric section, sew and repeat. When all sections have been added, trim off the outside edges, making sure to leave seam allowance on all sides. When your block is complete, it's time to carefully peel off the freezer paper. I generally try to go at a diagonal across the block. Going one way vs another will cause less threads to ravel off the seam allowances. Here is where you will have some real trouble, if you did not iron your paper to your pressing surface, at the beginning. It will stick so tightly to the fabric, you won't be able to get them apart. There are videos on you tube showing this method of PP w/ freezer paper. I make PP patterns with many small to tiny sections and ripping off the paper was a real pain and time waster. One hour to remove paper on a 6" block - "No thanks".
