Instruction

1

To determine the size of the future cardboard hats measuring tape measure the circumference of your head. Then, calculate the radius of the inner (smaller) circular part of the brim of a cap according to the following formula: radius = head circumference / 6.28. It will be a smaller radius. Now calculate the radius of the outer (larger) circumference of the brim of a cap, adding to the obtained radius of the inner part of the brim of a cap 25 cm (the width of the brim of a cap). It will be a larger radius.

2

Take a sheet

**of cardboard**and draw with your compass a circle of larger radius. Then from this point draw a circle of a smaller radius. Inside the circumference of the smaller radius, draw valves with a length of approximately 3 cm, which will further help to glue the field to the top of the hat. Cut out the inner part of the brim of a cap, leaving the valves.3

Draw a circle with a radius of 25-30 cm and cut from it the top part of the hat (about 1/4 circumference), leaving a flap for bonding the edges of the cone. Fold the top part of the hat cone and glue the valve to the other edge of the cone.

Lift the flaps on the inner circle of the brim of a cap and spread adhesive. Press the upper part of the hat to the brim of a cap valve. Cardboard hat ready.

Useful advice

- for the manufacture of hats, don't use corrugated cardboard (boxes from large appliances) because this Board is not flexible enough.

- the finished hat can be decorated with ribbon, Christmas tinsel or the application of colored paper
