Hi to all,
Finding the time to look at this great website now. I work on many projects at once - now knitting slippers to be felted, knitting a sweater vest, knitting a spring sweater, crocheting a blanket and finishing an English paper pieced quilt with a BOM group. I work on 3 of them a knit. it helps my fingers not get sore with one motion and keeps me interested.
Loved reading all of your replies.

I try to finish a project before I move on to a new one. There are times when I was working on a baby blanket and another project, but that is not my rule of thumb.
I enjoy working with two projects or some times three at the same time. It makes it more fun for me.
I always have two: a plain one like a fancy yarn scarf that u can knit without paying much attention, and a complicated one like a stuffed bear that absorbs a lot of attention.
Oh dear. I am guilty of having lots of started projects, but not so many finishedā¦ Iām knitting āThe Twigsā at the moment as my lockdown project and am determined to finish it - itās quite complex. And I always like to have something small, like some socks, that I can grab if Iām going out - though sadly not needed at the moment.
Fab question and fab answers! Love to hear how other people work their projects. Like books, Iām never happy with one on the go. I like a mindless one then a more tricky one and maybe something else too. So at the minute Iāve got a rainbow sweater for my niece, a cardigan for my sister and a baby blanket for charity on my needles (and a historical novel, non-fiction audiobook and fiction audiobook on my currently reading list). I donāt do much else so need the variety 
Iām enjoying reading everyoneās responses!! Iām so glad I asked this question!!!

So am I Knitcindy! It is a wonderful question and indeed fun to see the different ways of managing knitting projects. Good going.
Multiple if item is large. I knit smaller projects better. My patience are short
I knit one at a time but sometimes I make multiples of one item - like Christmas pieces. In that case I find myself making a variety of things but they are all interconnected. Great question.
I like to do multiple projects. Crochet, knit and cross stitch. When I tire of one go to another. They are easy patterns to pick up and go.
When I first got back into the swing of things, I did one at a time starting with a sweater but now I have multiple projects going. I am working on a spring blanket, a crochet cardigan sweater, and a hat for my dad. I am going to out of yarn after that as I am waiting for a couple of deliveryās from various companyās.
Have always done one project at a time, just like my mother. Saying that, I always know what my next knit is going to be!
When I said I have one project on the go with my next one plannedā¦Iām making a sweater for myself and then one for my husband. Or that was the plan! My sister (I have two) bought my mum a new mobile phone on which you can make video calls. So I video called her last night and I showed her the sweater Iām making and she decided she wanted one the same lol. So now THATāS going to be my next project instead lol.
Oh no!!! 
I am so glad you are getting better!!! 
Please take care of yourself and donāt forget your physical therapy!!! That will help get your hands back in shape for knitting/crochetting, whichever you chooseā¦ 
Right now I have several things going. I must finish the little sweater for my teddy bear who is more than 70 years old ā my sister made one and itās faded so he gets a new one.
Wonder when Iāll get a sweater going for myself ā¦
Right now, I have several unfinished projects (about 6 on the go!). I just finished a blanket not too long ago, but I started a top that has lots of instructions, then I started making some market bags, and I have about 3 unfinished blankets. I am working on my PHD in knitting (Projects Half Done!) LOL 
I do one at a time. I tried to start a sequence knitting project to work on after I got too tired of working on my main project, but that doesnāt work for me, soā¦
Iām also turning to my stash and saving a lot of money right now because of it. Unfortunately, that also means that Iām now knitting a sweater in some black yarn that I had planned for another project that I decided against making. Oh, well. Nothing wrong with a black sweater! 
Lots in progress but less frequently completed! I still owe my brother a blanket (curse his long legs!) for Christmas about 4 years ago 
and various other things were meant to be gifts but got abandoned for one reason or another. Starting to think I enjoy the process more than āmaking somethingā!
I finished a thinfinity (thin infinity) scarf yesterday and the matching fingerless mittens today, and am knitting squares for a blanket in chunky yarn so fairly quick to do, have half a front and long sleeves to do on a lacy bolero in black 4 ply cotton. I was waiting for extra yarn as I underestimated but have that now, and have just ordered 12 colours to do a temperature blanket. I like a few things on the go so I can chop and change as the mood takes me.
