Intro: Interchangeable Skins for Messenger Bags.
People love t-shirts but you can only wear a shirt once a week. This tutorial teaches you how to take an old t-shirt and turn it into an Evozip interchangeable skin that you can attach to your messenger bag. When you get tired of the design on your bag, just make a new skin and attach it to your bag. You can make your own skins from old shirts, decorate blank cloth, or trade with friends. Evozip is a new standard that lets people create skins for bags. You can modify your own bag and every bag fits every skin.
Step 1: Prep Your Shirt
Start with an old shirt that is washed without fabric softener. The design on your shirt should be roughly the size of an 8 1/2"X 11" piece of paper.
Layout a square that is 11" X 17" on your shirt and cut around the square. Lay the shirt on top of your interfacing and iron the interfacing to the back of your shirt. Follow MFG recommendations and use a pressing cloth to avoid sticking to the design.
You can use any one sided interfacing that you may have already. The purpose of this step is to give the shirt some strength and keep it from stretching.
Your shirt should now be bound to the interfacing and have a bit more strength than just the t-shirt.
Step 2: Draw and Cut
Draw a rectangle 14 3/4" by 9" inches on top of your shirt centered around the design that you want to keep. We use a plastic template, but you can use a blank piece of paper that is the right shape.
After you have drawn the edges, cut along the lines.
This is the quick method. You can add bias tape or ribbon to give the edges a finished look. We use a serger and add a canvas backing instead of ironing.
Step 3: Add Grommets
Now add the 1/4" grommets to the corners. Place the center of the grommet hole about 3/4" inch from each edge. There should be about a 1/4" between the edge of the grommet and the edge of your cut shirt.
It is important to use 1/4" grommets. Too big and the buttons may fall through the hole. Too small, and the shank on a shank button will not settle in the hole.
If you want to keep this simple, just make a small hole in the cloth that is smaller than 1/4". The hole just needs to be big enough for two pieces of thin elastic
Step 4: Add Skin to Bag
Your shirt should now be ready for your bag. Just put the buttons with the elastic through the shirt and into the bag and then put the loop around the tail of the bag button.
Next, we will teach you how to make the buttons and the bag.
