I've just started getting into sewing. Many sources of PDF patterns seem to have one that's free so you can see what their patterns are like, e.g. I used
Walk the Plank PJs as a starter project, and I'm currently working on
Roemeria Pants (which I've printed, assembled, and coarsely cut out and am now working on adjusting).
They seem to commonly come with 3 options (though check, not all will have all of these):
- Letter Sized (and A4) for printing at home
- A0 for a large format you can get printed at a copy shop and some sewing stores now offer this service as well.
- Projector files you can use to trace onto paper without printing - there's a whole projector set up you need for this, I have not investigated.
They usually have a sizing square you can check, and a guide of which pages you need to print for different sizes & options. Many have layers in the PDF which let you choose to print only the size(s) you want. Depending on the pattern you may or may not need to trim the pages before taping them together, and they seem to do different things to help you line them up. Both of the ones I've done so far have labelled each page with a letter/number like "B3".
I've done it by printing letter sized pages at home. Carefully lining up and taping 40 pages together does take a bit of time, but was a nice simple calming activity. It probably happens that you can get out of alignment in a way that ads up but the tissue paper patterns seem to fold and crinkle easily as well which could cause similar issues. Walk the Plank is just one very large piece at 1X and while some pages were definitely slightly off by the time I went to add the next ones, it was all fine in the end. For Roemeria, which has a front and back leg piece plus lots of smaller bits, I cut out chunks of pattern pieces as I was assembling so I didn't have to deal with more than about 3x7 pages at a time.
The sewing store near me charges $5.50 CAD per A0 page, I expect copy shops may be cheaper. The Walk the Plank fits on 2 A0 pages (which need to be taped together), the Roemaria are on 2 for "regular" and 3 for "plus" sizes (but all pattern pieces fit on a single page so no taping). If you need to get it printed somewhere anyways I'd do that!
I do need to figure out a good way to store them as they can be quite bulky. I traced out the Walk the Plank pattern with my adjustments onto some lighter weight slightly transparent paper I had on a roll (not sure what it was originally purchased as - a little heavier than what I'd call tissue paper).
There's lots of indie pattern companies now that only do PDF, and the companies that offer both PDF and printed often have a wider size range in PDF.
