Ah! While I was waffling on, I see Andy got 5 and Daniel solved 4. Brill! I'll post 'em up now.
1. hem = skirt (Chambers & Ox Thes’i); AHEM = used to draw attention to oneself (Chambers def)
2. (double) FOUNDERS
3. Subtractive anag (away & wrong) of “stole one to do” – “sent” = TOODLE-OO = goodbye = so long.
4. bb = books (Chambers def); about = re; bbre (so far); flying = aviation; books about, flying around = a(bbre)viation = ABBREVIATION = GB, say
5. bill = poster; a flyer = a tern; bill a flyer put in = p(a tern)oster =(to give) PATERNOSTER = a lift for goods or passengers .... (Chambers def)
Thank you all for participating. See you next week (I'll make a mental note on a piece of paper, to help me remember). lol
