Album labels

I have all my matching American Craft albums standing upright and have trouble telling which is which without pulling them out to look at the cover.

I decided to make these cute tags but I am needing some suggestions with how to attach them.

Should I punch a hole and use string to loops from the inside ring...or use a clip of some type. I would like to leave the small cloths pins but they are only temporary bc I dont think they will stay on.

I would love to hear what YOU think I should do...
