Choose your box to hold your rings. It should be deep enough to hold your largest ring. If possible, use a box with a lid to keep your rings safe. I used an UB Primer Potion box here.

Measure the width of your box.
Mark it on your t-shirt and cut long strips. Remember that the longer your strip the bigger the roll.

Roll up your strip leaving room to glue at the end.

Before gluing,place some rolls in the box to see how many more you will need.The rolls should fit snugly together.

You may need to cut off some fabric for the roll to fit into the box. Do this with scissors.

Place a line of hot glue on the roll and attach the end.

Place a line of glue on the bottom of the box to secure each roll. Remember to fit them snugly together so your rings don't fall out.

Then you're done! all you need is to put your rings inside.
