They’re fun to play with, painful to step on, and something that just about every household probably has laying around:  Legos!  The iconic snap-together blocks have been a classic toy for eons, and will most likely continue to be popular until the end of time.  Make a playful statement by turning a few stray blocks into jewelry!  Instructables user jessyratfink made these necklaces, as well as earrings and a bracelet.  Add a gumball machine toy necklace to the mix and proudly show off your inner child.  [how to make DIY Lego jewelry]
