This top came from an old Kwik Sew master pattern book. It's a basic sweat top.
I used up some scraps of fabric. The gray and blue in the shirt is some med weight sweat shirt fabric and the sleeves are a lighter weight sweat shirt fabric. I used black rib knit for the neck and the waist hem. I took some design liberty in in the blocking. I basically put my traced pattern on the scraps to see how much fabric I had. Then I cut the pattern up, placed it on my scraps, eyeballed some seam allowances and began cutting and sewing.
