This is the perfect DIY project to do when you have no supplies and time to kill.
*5/6 inch long twigs
2. Grab some colorful twine and cut 2 pieces that are about twice the length of your coaster.
3. Fold each string in half. Place a loop at each end of your 1st twig and tie two knots. Continue the process until all of your twigs are tied together.
4. On your last branch, tie 4 knots and trim the twine
5. Enjoy your brand new coaster, (or mini raft as we like to call it)
