The following clues form a word chain. The last three letters of one word or phrase form the first three letters of the next word, and the list wraps round from the last word to the first. Mostly straightforward with the odd one needing the Stitchionary, but there may be one or two hyphenated words, alternative spellings or short phrases in there, and remember it was compiled by a Brit.
Quite a short one this time (I found a fortuitous "wrap-round" early on, and wasn't going to waste it!) so just a couple each to start with, pretty please.
