I don't know if the green ones will dry but the red ones can be strung up individually to dry by taking a needle and thread and putting the thread through the stalk bit, put about 8 on a thread with a space between them and hang them up somewhere dry like indoors. They look very decorative and good for Xmas decs too! Oh no I said the forbidden word!
I tried overwintering a chilli plant indoors but it died on me.
