I bought a couple of these stars to make my own toys with. The stars themselves are a little on the small side, great for my Amazons. There are six holes to hang a string from, five on each point, and one in the center. Each "arm" on the toy I made (pictured, please forgive the low quality) could have been supported individually, but for a heavier toy, I would suggest anchoring each one to a single point to help alleviate stress on the star. Although quite sturdy, I am unsure how the star would hold up to six macaw sixed arms.
