How can I cinch my Ursack completely tight?
First. Starting from the grommet opposite the grommet where the cord lock is, pull the cords tight, then pull one cord at a time to tighten it further. Second. Wrap both cords (beyond the cordlock) around something sturdy–a tree branch, a strong door knob etc. Then pull steadily (don’t yank) until the opening is securely closed. You won’t break the cords, the grommets or the bag doing this.
