Anybody who knits observes a few necessary traditions: the winding o’ the yarn. The knitting o’ the swatch. The photocopying o’ the pattern. Making a copy of the pattern is the only way to keep those pattern books from falling into decay or, worse, actual use.
Well, there’s another ritual I encourage, when you’re heading into a project with a significant lifespan. Go to the copy store and pay up to preserve your precious Fair Isle chart or lace stitch chart or hell, the whole pattern.
Make like a kindergarten teacher and laminate.
Those stiff ’n’ shiny layers of hi-kwalidy wipe-kleen plastic will spark joy every time you re-start your gargantuan project.
