This is not going to help.

Very,very,very basic. just a few simple knots included

Defective! I gave this to my son in his Easter basket to help him finish earning his Fishing Merit Badge and have it to fish with Grandpa this summer. Unfortunately, 2 out of the 3 cards put together were the same and therefore didn't match up for the ruler and didn't have all the knots advertised. I'm very dissapointed that I am not being given the option to return this, even though I purchased it only a month ago (I try to spread out my purchases like a financially fiscal person).
