Let's make the wristband for @boardname@!

## Duration: ~ 1 hour 

## Step 1: Creating the wristband for the battery pack 

From your piece of paper, measure and cut a strip that is approximately 3 inches x 10 inches. It's okay if your strip is not exactly 10 inches!

Using duct tape, cover both sides of this strip with tape. Be creative and decorate the strip however you want! If you want to put on more stickers or use glue, make sure you leave enough space on the left side of the strip to attach the velcro. Also, make the rectangle in the middle about 3 inches wide so that you can still attach your battery pack.

After you're done decorating, paste 2 velcro sqaures or circles to the top and the bottom of the **LEFT** side of the strip.

Flip the strip over on the long end. Place the other side of the velcro squares or circles on the **RIGHT** side of the flipped-over strip. 

Flip the strip back over. You should have a strip with 2 pieces of velcro on the **LEFT** side facing up at you. The velcro on the **RIGHT** side should NOT be seen unless you flip the strip back over. 

Cut a rectangular piece of cardboard that is 4.5 inches long and 2 inches wide. Once again, this doesn't have to be exact :)

Lay your battery pack in the center of the cardboard. Your setup should look like this.

Use the shape of the battery pack to form the cardboard - your cardboard should make a U-shape around the battery pack. Here's a video to show you how to do this!

Using the hot glue gun, attach the two flaps onto the wristband. Leave the battery pack in place. This  helps you determine how far apart to glue the flaps so that the battery pack fits snugly into the cardboard.

If you have any scrap cardboard left, cut a small rectangle out so you can glue it to the bottom of your folded cardboard. Here's a video demonstrating what we did that!

Your wristband is done now! Let's get on to making the hand strap for your circuit player.

## Step 2: Creating the hand strap for @boardname@ 

Cut a strip of paper that is approximately 2.5 x 9.5 inches. 

![Hand strap](/static/cp/projects/reaction/hand-strap.jpg)

Fold 3 inches of the paper from the short side in.

Using scissors, on the fold, cut a half circle to a half oval. This creates a hole for your thumb so that you can wear this as a hand strap!

<br/>
Unfold your paper. You should have a full circle now! If the circle looks too small for your thumb, refold your paper and cut a bigger half circle.

Using duct tape, cover the inside of the circle so that there are no worries about the paper cutting your thumb.

<br/>
Now, use your duct tape and your creative instincts to finish covering both sides of the strip with duct tape! Remember to leave the thumb hole uncovered from tape. 

Take two velcro squares or cicles and paste them on the right side of the thumb hole you just cut. 

Flip the strip over on its long side, and paste the opposite sides of the velcro on the left side. 

Attach 1 or 2 pieces of velcro on your @boardname@. If your velcro pieces are large, use just 1! If they are smaller, use 2. For this example we attached 2 to our @boardname@. 

Place the opposite sides of the velro in the center of your hand strap.
