Okay so to save your own items - go to that little arrow beside your name. The options to download or upload or whatever are there. It was a bit tricky to figure out but this set is made entirely of items that Hilart and I made for Polyvore (she did the original image and I edited it for use on Poly). I have a lot on my computer and it will take time to add it all but it is in an album that my friends can access.
