Picking up stitches

[ebrperk]

I am making the duck blanket by Bernat. It says to pick up 124 stitches on the side to do a ten row garter stitch border. I have more rows than that. Do I just pick up one in every row. I am not too worried that it will be bigger since it is kind of small and I am using a no dye lot yarn so getting more is not a problem but I didn't know if I should skip some of the stitches or go ahead and pick them all up.
