Yarn advice

Hi I have a pattern for a child’s jacket I would love to knit. However it states use worsted wool and to use 3.5mm needles. Question is if I buy Aran wool instead (as cheaper) would I need the same quantity and would I use the same size needles? Thank you :slightly_smiling_face:

Aran and worsted are going to be pretty close. The best way to figure this out is to knit a swatch with the yarn. Then you can figure out which needle size to use to get gauge and determine whether you like the feel of the knit fabric.

Thank you I will try that. :blush:
