I thought that, in this craziness, knitters might be seeking projects that aren't too big, not too involved yet not boring, knittable from stash, with easy and fast finishing, and just generally FUN to knit. So here's a thread of patterns I think tick those boxes - add your own!
Of course a few of these suggestions will be my own patterns. :) This toque takes about one ball of 50g of DK weight in each colour (although somewhat more is needed for the main colour if you do the large size). https://www.ravelry.com/patterns/library/lavagna
This scarf is soothingly basic, yet the end product is so fun. And it's really flexible, you can use pretty much any yarn weight you want and use any number of colours, so it can be a great stashbuster, too. https://www.ravelry.com/patterns/library/latifa
This was an absolutely delicious knit to make - I flew through it and could have happily done another one. If you've got two different-colour 100g skeins of worsted weight in your stash, you're good to go. https://www.ravelry.com/patterns/library/jimi-shawlette
If double knitting is your thing, this is a nice time-passer. You'll need about 155 yards of each of two colours of DK weight yarn. https://www.ravelry.com/patterns/library/jianzhi
Here's a free pattern which is short and sweet and holds your interest - mine took me 123 yards of the main colour and 80 yards of the contrast colour. Fingering weight. https://www.ravelry.com/patterns/library/winter-forest-cowl-2
Depending on your yarn hoard, this might not be stash-knittable, but it does tick the other boxes. It takes two colours of worsted weight yarn - in the neighbourhood of 550 to 750 yards of each colour, based on your size choice. https://www.ravelry.com/patterns/library/corbichon
These fingerless mittens whip up fast and are super-pretty. You'll need 120-200 yards of fingering weight. https://www.ravelry.com/patterns/library/regina-marie-mitts
This tam takes worsted weight yarn - you'll need a 100g skein of the main colour and a 50g skein of the contrast colour. https://www.ravelry.com/patterns/library/beaulieu
You wouldn't think a cardigan would be a "not too big" project, but I've done two of these and they flew off the needles with NO SEAMING. If you've got 730-1530 yards of fingering weight in your stash, it's a lot of fun. https://www.ravelry.com/patterns/library/hitofude-cardigan
My oldest daughter loves the hat I made from this pattern. I only needed about 110 yards of worsted weight cotton to pull it off. https://www.ravelry.com/patterns/library/sneaky-snakes
I really enjoyed watching the lace pattern on this tam take shape. Mine used about 212 yards of fingering weight yarn. https://www.ravelry.com/patterns/library/wasabi-hat
Another of my patterns, this one is free! You'll need three colours of fingering weight yarn, about 25-30g each, it's a great stashbuster for leftover sock yarn. https://www.ravelry.com/patterns/library/round-the-blend
This lace shawl pattern is the very definition of fun, gobble-it-up knitting. It calls for 500yds of DK weight, but because it's knit outwards, if you don't have quite enough, you can reduce the length of the edging. https://www.ravelry.com/patterns/library/wavedeck
That's all I've got for now - if I think of more, I'll add 'em. Hope this helps!
