How to Decorate a Baseball Cap with Mini Quilt Blocks

Do you have a plain baseball cap that you don’t wear very often? Why not change it up a little bit and embellish it with a few mini quilt blocks. It is easy. In my tutorial you’ll get instructions for three different blocks and how to attach them to the cap. So if you are interested in adding a little bit of your unique style to your wardrobe, learn how to decorate a baseball cap with mini quilt blocks.

I came up with this project when I was making my June Island Batik Ambassador quilt. It was a New York Beauty challenge and I was given their gorgeous new fabric line called Tranquility which was designed by Deb Tucker’s Studio 180 Designs. After finishing the quilt, I had pieces of the 20 different fabrics left over, so I decided to do something with them. That is how my ball cap was born. Not only that, but I had enough left over to do a little giveaway. Read on until the end to get the info!

Preparing the Blocks for the Hat

Fold over the edges around all four of the sides of the block 1/4″ towards the back (wrong side) of the block. Press or use fabric glue to help keep edges down. This step is a bit tricky.

Caution: If you press, do not use steam and keep your fingers far away from the iron. The iron is hot and you will burn your fingers.

How to Decorate a Baseball Cap With the Mini Quilt Blocks.

Decide where you want to place the first block on your cap. Pin into place. Watch out because most caps have a rim around the inside and you don’t want to sew that down.

Using about an 1/8″ seam, stitch around the four sides of the block. There is a lot of manipulation needed so I recommend stitching slowly.

Add the second block where you want it to be. Mine went on the opposite side.

I wanted a block on the front and decided on the Bear’s Paw. I had enough room to put it on the diagonal and used the cap’s seam to help me line it up. The front is the hardest because of the hat’s bill. Sew slowly and carefully.
