Step 1: Cut the Collar

To make the ruffled collar, fold the blue fabric in half lengthwise. An inch from the folded edge, sew a gathering stitch and leave the thread at the end.

Step 2: Cinch Ruffles

Pull the end threads to gather the fabric. Stitch the neck edge to hold the gathers. Sew a piece of ribbon at each end. Make sure each piece is long enough to attach the collar.

Step 3: Make the Poms

To make your own yarn pom-poms, wrap blue yarn around your hand several times. Slide off your hand and tie a piece of yarn tightly around the middle to secure. Cut the loops of yarn, and fluff into a pom-pom, trimming any long yarn ends for a uniform look. Don't worry about making too many: There are so many ways to use pom-poms! When you're done, hand-stitch the pom-poms to the shirt.

Step 4: Paint the Dots

Use the paint marker to decorate the long underwear. Add spots all over in a contrasting color, or switch it up by painting multicolor spots!

Step 5: Make the Hat

Roll a large piece of poster board into a cone shape. Overlap the long edge, and cut off the excess; hot-glue into place. Hot-glue the three blue felt balls to the front of the hat. Punch a hole along the bottom edge on each side and tie a piece of yarn through each hole. These strings will tie under the child's chin.
