When my brother had been with his girlfriend a few years, I started a baby blanket with the thought that they’d probably be thinking about kids soon, being in their early 30’s. They got married a year or so later and their first kid is now 3.5 years old - that blanket’s still not done 🤣 maybe for the next one. I did manage to finish one, sort of, for the unexpected baby I had myself last year - I intended to use three cakes of yarn so it’s toddler-sized. Got to two, decided that was fine and I can always extend it.. the last row wasn’t finished because the yarn ran out midway and I meant to just finish it with a matching solid colour and never got round to it (I sell yarn so it was just a case of picking it up from the storage shed in the garden and bringing it in and doing half a row of sc..) The ends aren’t sewn in either but she doesn’t seem to mind!
