Easy to make memory card protection/organization! Can be adapted for almost any memory card I made mine for use with Memory Stick Pro Duo's. It can hold 8 Pro Duo's in a space just bigger than a credit card. I have to estimate for the other formats but I'd say 4 Memory Stick's/6 SD/2 CF; I wouldn't make this for smaller formats (SD micro/mini,XD...) .
Line up the card on a strip of tape leaving a small amount of the card hanging off enough to grip.
Step 3: Making the sleeve.
Take your strip of Duct tape and roll it around the memory card, you want it snug but not to tight. One side of the roll will most likely be wider which ever end you did not hold when rolling. You will want to place that end towards the outside.
Step 4: Put it all together.
Here is where you get to be creative i used some empty Metro cards, you could do it simply with a piece of Duct tape on either side. And that's it, enjoy.
