Michigan Stamper: Other people have been using E6000, a strong glue that I believe comes in a tube that is primarily used for jewelry making; however I didn't have any of that, so I just used a hot glue gun. These are 2-sided, so I just put one piece of chipboard face down, and placed the paper clip on top. I then liberally applied hot glue on top of the paper clip and made sure that the glue oozed down onto the chipboard (I did this in 3 places). Then, before the hot glue dried, I placed the other piece of chipboard on and squeezed just a few seconds to secure. I've tugged on these fairly hard and they seem secure. HTH!
