Just a quickie show... I tried to make onions. I did find some on EBay, but have always been outbid (I'm such a scrooge - hate paying out too much *lol*).
My onions aren't too bad... though I rather stupidly made onion canes and made these with a 'skin' on them - though it doesn't show too much. My red onion cane is a complete disaster... I think that using plain translucent is a mistake, and if I try this again I'll mix it with a little pearlised white clay too.
The whole onions are made from the cane - so if they are sliced, they'll look like real onions inside - well, sort of :)
