As a comparatively new crocheter, I urge anyone to crochet them together (at least in strips) as you go; having 200 hexagons to put together does not encourage completed tasks! And using random old scraps of different yarns (different ply wools with acrylics) can lead to washing disasters, a real shame after all those hours of love.
Local retirement homes and hospices will always be pleased to receive donations of shawls, lap blankets and twiddle blankets and muffs.
For those of you who long to learn crocheting (I was that woman a few years ago, dear reader), I learned at local craft shop, but local librares have crochet groups who always welcome new unskilled members - you only need chain, doubles and trebles! And YouTube is great for learning to crochet.
