Make one long piece out of the sides of the Beer Box. Cut off the Beer Case top with scissors if it's attached. Cut along the one corner of the side from top to bottom. Cut the bottom of the Beer Box off completely. That leaves the sides of the Beer Carton intact as one long piece.
Measure the cowboy's head. Wrap the long piece from the sides of the BeerBox around the head of the person the hat is being made for. Make a pencil mark on the cardboard where the edge meets the other end after encircling the head.
Use the edge to cross the head measurement pencil mark. Hold the edge at that angle and use it to mark another line.Cut along the angled mark. Wrap the cut portion around the head you're fitting until the edges meet to make sure of the size.
Cut the point off the angled cut. Bring the edges together at one point and cut the excess off so the other points meet. Use packing tape to hold the seam together.Place the wide part of the taped ring on the center of the Beer Carton top. Draw a line on the Beer Box top around outside of the ring.
Poke the scissors through the Beer Box top at one point on the line and cut out the ring. Keep both parts in tact.Cut off the corners on the Beer Box top. Make the corners into rounded edges to form the brim of the Beer Carton Hat.
Stuff the circle you cut out into the taped sides. Push it in from the big end until it is close to the smaller end.Tuck the bigger end of the sides into the hole in the beer box top. Curl the edges of the brim for a genuine Redneck Beer Hat appearance.
