Colin - Mamya is apparently the expert knitter (biscuits have been mentioned, don't ask me how she does it!?) Odd thinbgs happen on this site but you usually do get the answers to your questions - who can ask for more!
Mamya - I understood from Trevor's post that you were in an institution (albeit one which gives you some freedom in the knitting needle and PC department) If you are on the loose with knitted bagpipes and biscuits we all need to be afraid! (I was also hoping that Trevor the vaseline tiger was in the comfortable room next door)
