If you're at your McDonald's and the kid's need some entertaining, try weaving a heart out of some straws. All you need is two straws and scissors. You could also weave this heart from paper strips. Cut the strips to about 1 cm thick and 30 cms long. Follow the video tutorial on how to weave the heart below. This would be perfect to make one our two and stick them on a home made Valentine's Day card. You could also string them together and make heart garland.
