First Sweater Finished

I have been working on DS2's sweater every available moment and it is done. It looks really nice. Only problem is it is huge. I pulled a total beginner mistake. I didn't take time to check the gauge. I was anxious to start for one reason. The other is it honestly didn't occur to me. I have knitted on sport weight so long I assumed it was the same. Totally spaced the fact that it was a different brand of yarn and might have a different gauge.

I am just going to have to see how it looks on him Christmas morning. If it is a little baggy it might be okay, if not I guess I will be re-knitting.
