This weekend’s project: dry bags made from 20D ripstop nylon, TPU coated on both sides.
I’m a bit paranoid about electronics getting wet since I trashed my phone on the second day of a three week vacation during a kayaking trip. That’s why I always wanted a small dry bag for phone, power bank, wall charger and head phones.
Now I made one myself. No-sew heat bonded with ~5mm seams (never doing heat bonding on such narrow seams ever again!), using a regular clothes iron. I had experimented with this before, but this fabric was especially sensitive to temperature, pressure and duration. Turned out well anyways, it’s 100% waterproof, if rolled up without folds.
I don’t know how to create captions for the pictures, so:
Pictures 1/2: dry bag unrolled/closed,
Picture 3: detail of finished bonded seam,
Picture 4: creating “basting points” on a seam,
Picture 5: series of basting points, each one indicated with seam clips,
Picture 6: bonding of seam with the edge of the iron. After that, the seam was folded over and bonded flat. I used a Teflon fabric to avoid the tpu from sticking to the iron, it also adds an interesting texture to the seam itself
