My youngest had a birthday card with a Tardis on the front; when you opened it there was a device that said “exterminate, exterminate” in a dalek voice!! (hours of entertainment for him, months later when it was still going strong it did get a bit irritating!!!) I wondered if you could incorporate one of the little disc shaped devices into your knitted daleks? good luck with all the christmas knitting and sewing! One blog spot has a countdown of days left until Christmas - I am now excited and anxious in equal measure! see you soon. X
