DIY tyvek stuff sack
1 tyvek envelope
Pair of scissors
Braided fishing line
Needle with large eye
Step 1: Envelope
Start with a tyvek envelope. Cut off the flap.
Step 2: Cut
Cut a 1 inch slit down one of the top sides. This is where your rope will come out when the stuff sack is finished.
Step 3: Fold
Fold the top over.
Step 4: Rope
Cut rope to be about 4 inches longer than the envelope is around. Singe the ends of the rope with a lighter and pinch to seal so the ends don't fray.
Step 5: Position Rope
Place the rope under the flap.
Step 6: Pin Flap
While rope is still under the flap, safety pin the flap closed.
Step 7: Sew
Cut a piece of fishing line that is two and a half times the length that the envelope is around.
Thread the needle with the fishing line and then tie several knots at the end to create one large knot to hold the line in place when you start sewing.
Start sewing between the rope and safety pins until you have sewed all the way around the flap. Make sure you secure the last stitch with several knots to keep it in place.
Step 8: Add Cord Locks
After the fishing line has been sewn in and knotted to keep the line from coming undone, add a cord lock to each end of the rope or one large cord lock with both ends threaded through.
