Easy Relaxed Pullover Using Rauma Alpakka Lin

I’m enjoying making a swatch with the yarn. Nervous about quantity. I got 5 skeins for a medium sweater. Looks like I’m getting gauge on size 10s. If I wet block it, will the gauge be a bit larger? (1/2-1stitch more?) I’m getting 6.5 stitches to 2 inches.
