|While tracing may work for some, personally I find direct cutting MUCH easier. If you own a scanner as I do, you may find scanning individual pattern pieces easier than tracing.
If you make a scan, you don't have to destroy the original. With multi-sized patterns that you might make more than once—especialiy for a growing kid, this matters. Scanning also provides an alternative way to store pattern pieces.
While many pieces will fit on the scanner bed, some may have to be scanned in parts and then scotched taped together. Personally I find this chore less of a pain than tracing, though I admit for big-pieces it is not a 'piece of cake." Still, the hardest part for me was cutting apart the big beautiful sheet of pattern pieces!
Once the pieces are printed out, you can 'highlight' the size you are cutting with a squiggle. ( See picture above.) This is particularly helpful in places full of little triangles that frame the tabs/notches on the pattern pieces.
If you do try this, be sure to check your printer's settings to be sure you are printing 100% and not enlarging to 'fit the page.'
I notice that Jalie publishes out-of-print patterns as pdfs. Perhaps eventually we will be able to get all of them that way... I hope so.
