I got the taller plastic test tube from a site in the US ages ago, http://www.silvercrowcreations.com/ and must see if I can get some more. The smaller tube was from a crafty resource centre I visit now and again, but they are both perfect for Halloween trick or treat favours.
The tags are made using my Stampin Up scalloped and plain circle punches which I have decorated on both sides with Accessorize stickers and handwritten messages using black and white gel pens.
The tags are on a thread, kept in place by a piece of black and white gingham ribbon (now deleted from Stampin Up range) at the top of the test tube.
The tube is finished off with a large purple flat backed gem stuck on the cap.
The jelly beans are from the Original Jelly Bean Factory, they cost a bit more than ordinary jelly beans, but they are smaller and I can buy just the colours I need in their pick and mix section which gives this idea a lot of its charm.
