I made one... and you can too!
Here is how you can take a plain cap and make it an original masterpiece - in about an hour.
Start with a plain cap. You can purchase a new one, or go to your trusty ball cap collection and re-purpose one that you already have. Which ever you choose what you end up with will be beautiful and unique!
Cut pieces of fabric scraps into designs that you'd like to see on your hat. I wanted a floral theme on mine and happened to have a piece of fabric with flowers printed on them. Press the pieces with an iron to eliminate any wrinkles. Place the pieces on the hat in the positions that you want to adhere them in. If you can, try to put the cap on your head so you can see what it looks like on - sometimes it makes a difference in how the final placement looks.
When you are happy with the placement, use fabric glue and tack down fabric in the center of the piece. Do this will all pieces. Once all pieces are tacked, use a brush or toothpick to apply more glue to the edges of the pieces. Note: My glue favorite is Gem Tack Flexible glue by Beacon - it's for adhering gems, but works wonderfully for this project.
Once they have dried, use a tooth pick to place dots of glue around the edges of the fabric and adhere rhinestones. Let it all dry - and in about an hour you have a fantastically fashionable cap!
