EthelJ I took up knitting again in my 50s not having knitted since I was a child and it has been such a pleasure. I started with a straight scarf but quickly progressed. There are some easy patterns on Ravelry, you can select patterns on there via filters, to suit your level of expertise.
Just don't do what one of the novice knitters did in a group I went to for a while - she had knitted a beautiful scarf in blocks of different stitches (to practise them) - and then she jolly well ruined the whole thing by pressing it with a damp cloth "to make it lie flat" - I felt so sorry for her, no one had told her that you never iron or press knitting. So a couple of tips for finishing:
When I've finished knitting something, I squish it in wool wash by hand, take it out and squeeze to get most of the water out, and then I lay it out on a towel and roll the towel up and walk on the roll of towel
after which I unroll it and put the garment or scarf or blanket or whatever it is on a drying rack, lying flat.
I have a friend who is an expert knitter and once whatever she is knitting is finished, she carefully rolls the knitted object up, evening out any curled up edges, and leaves it over night.
Good luck and enjoy.
