Instead trace a copy onto thicker paper stock or card and transfer the pattern design number, size you’re tracing, notches and markings. To make it easier to transfer details in the future you can cut or punch holes in the card then you can easily pop your tailor’s chalk pencil or water erasable pen through for each important mark.
Tissue paper copies
Prefer something lightweight and slightly sheer? One of the perks of tissue is how you see through it for fabric print placement. Also with lightweight fabrics it can be easier to pin them to a lightweight tissue avoiding distortion for slippery silks or floaty chiffons.
Pick up a pack of excess tissue paper from Butterick and trace a copy that replicates the original pattern! A pack of 5 Sheets (76cm x 127cm) costs £1.95 from sewdirect.com. Or try Swedish Tracing Paper which is a slightly more robust white tissue paper that you can still see through and can also sew into a quick toile.
I’ve also had success with applying fusible interfacing to the back of pattern pieces. You gently press the pieces with a dry iron, pin to the fusible and cut out the shape, then fuse the two together. The trick is to use a dry iron as wet paper will not fuse, use a pressing cloth to avoid ink transferring to your iron or board, and to fuse until the glue has fully melted.
The reason I don’t often recommend this method as fusible interfacing can be pricey and better kept for use in dressmaking projects! Good in a pinch or if you’d found some on sale.
If you’re not someone who can neatly refold all your pattern tissue sheets in seconds like an OS map, you may struggle to fit your tissue back in its envelope. My top tip is to squash your folded tissue with a warm iron to flatten it back into shape ready for the original envelope. But you can also upgrade to an A4 envelope with plenty of room for pattern pieces, instructions, hacked copies of the pieces and more. I love the envelopes from www.patterntrace.com that have an expanding gusset and cover sheet front with space for pattern imagery and notes.
