childs sweater

is it possible to adjust the size of a sweater by increasing the needle size. the sweater I would love to make for my grand daughter only has up to size 18. months. and she is wearing everything 2 or 3…

It may be a bit larger, but it will also make the fabric looser so you have to take that into consideration. You might be able to use a heavier weight yarn and bigger needle. It also depends on the pattern. Can you give us a pattern name and link? (Don’t post the pattern itself because it’s against copyright)
