I finished ds’s sweater today. I’m a little disappointed in the measurements. The sleeves are too long and the body is too short. But it does sew up evenly, so at least there is that. Considering that it is my first sweater and I was using a pattern where I had to extrapolate his size AND not using the recommended yarn or needles, it isn’t too bad. I used a Debbie Bliss pattern from The Baby Knits Book and used size 11 needles with Plassard Rhapsodie yarn (until I ran out and then used something else, I don’t remember what, for the maroon on the sleeves). Anytime the pattern called for a certain number of stitches I used the newborn amount but when it called for length (like, st st until it is 6" from cast on edge etc) I made it the next increment beyond the 12 month size (the pattern went up in predictable increments, like 12 cm for newborn, 14 for 3-6 mo, 16 for 6-9 and 18 for 12 mo so making 18 mo should be 20, right? That is why the body is so short!)
Is there any way to add on to the bottom of the body with another yarn so it is longer?
