Making a beard out of yarn can be a simple craft project that will not take much time. Adding a fake beard to a costume can add character and you can save money by crafting your own from a few simple items that you can pick up at a craft or fabric store. If you knit or crochet you might have most of the material on hand.
Cut the felt in a beard shape. You will want to fit this to the face. An adults' fake beard will be bigger than that of a child. Adjust size accordingly.
Cut yarn into lengths of two to three inches. For a more realistic looking beard two or three different colours of yarn can be used, such as grey and black, yellow, brown and red, or any colour combination.
Lay your sticky backed felt flat on a smooth surface. Remove paper from felt. Make sure the sticky side of the felt is facing upwards.
Start at the bottom of the felt and gently press yarn onto the surface. Working left to right from the bottom of the felt cut-out fill in with yarn until all of the sticky side of your felt is covered.
With your scissors make two small holes on either side of your yarn beard. The holes should be where the beard comes up on your cheekbones, near your ears.
Thread your elastic through one hole and knot. Hold the beard up to the persons face that you are making the beard for and stretch the elastic around the back of his or hers' head.
Thread the elastic through the other hole in the felt and tie. This can adjusted by simpling retying if needed. Cut the excess elastic off.
To make your yarn beard fuller glue yarn to the back of the felt. To make the beard wave unwind the yarn after you have applied it to the felt.
