Step 1: To create the pattern, I laid an existing sweatshirt that was slightly too small on top of my fabric and traced around it with my trusty Crayola washable marker. I added about 1/2" to the face side of the hood, and 1/4" elsewhere for seam allowance.
Step 2: Sew the shoulder seams together. You will notice that I was lazy and used the serger and also that I was crazy lazy and didn't bother to change the thread color. This could totally be made with a sewing machine (and matching thread).
Step 3: Sew the sleeves in. I am too lazy to pin in place and try to eyeball in the middle. If my sleeves are too large for the sleeve holes, then I try to add a little gather near the middle to make it look like I totally planned it :).
Step 4: Sew up the sides and sleeves.
Step 5: Sew the hood pieces together (right sides facing).
Step 6: Hem the face side of the hood (the straight side). I used 1/2" hem and a double needle for a decorative finish.
Step 7: Sew hood onto neck (right sides together). I made sure to mark the center of the neck to ensure that the hood went on evenly.
Step 8: Cut a tiny V. Mine is about 1/2" wide and is the length of the v I cut into the front of the sweatshirt.
Step 9: Place V right side down on top of sweatshirt, and sew in place. I used 1/8" seam.
Step 11: From ribbing, cut 2 sleeve and one bottom piece. I used 3.5" length for both. Sew sides together for each piece, creating three circles.
Step 12: Fold ribbing in half (wrong sides together), and sew onto bottom and sleeves, making sure that seams will be on the wrong side of the sweatshirt.
