I make heaps
just use your imagination and make sure it's safe for the birds
i plaited rope and sewn buttons on it, i have also done the same with wire threaded through and made rope swings ect...
endless creations and cheap too
there are a couple of good posts in the photo forum on this subject
my main thing i do is look in pet shops for ideas the got to the local discount shop for things to use the one thing i seem to find the birds really love is the dog chew toy on a rope
