The key to success in creating your own baseball cap is proper measurement. Make sure to measure the circumference and height of your head carefully. One way to make this a little easier is to use an existing cap, if you have one, as a guide.
When you are cutting the triangles for the dome, their combined bases should be equal to the circumference of your head plus a few extra inches for overlap. Their heights should be about the distance from your ears to the top of your head plus about an extra 1/4 inch or so to form a hem.
The brim of your hat should be cut to match the contour of your forehead. Use an existing cap as a guide to help with this. Choose a cardboard or plastic that is soft enough to sew through but sturdy enough to hold a shape.
Finally, do not forget to cut out ventilation holes in the dome of the cap. Embroider the edges of these to prevent fraying.Learn more about Crafting
