Using two different yarns

Hi everyone
I am knitting a child’s striped pullover. I have both patons astra dk and sidair snuggly dk in my stash. Wondering if i could use both yarns for the project or should I go out and buy all of the same

I would think the dreaded gauge swatch might be in order here. Do a swatch to see if they knit at the same gauge. If they do, then you are good to go.

Make sure they have the same care instructions too.

Yep, a gauge swatch is the only way to know for sure.
