DIY felt crafts are a fun and low-cost way to try out new crafting techniques, such as making envelopes for handwritten letters. Sheets of craft felt can be picked up for around 20 cents each at craft stores, which makes the entire cost of this craft less than a dollar. Embellish envelopes with a button and bakers' twine, and secure the edges with hot glue. Creator Kelly suggests using these cute envelopes for love notes or gifting jewelry, and the felt envelopes template may be sized larger or smaller for custom-fit DIY felt envelopes.

Whether you are working with inexpensive craft felt or luxurious felted wool, you'll appreciate how forgiving it is to craft with felt, a material that hides mistakes with its thick fibers and plush texture.
