Anyway, they are really quite simple to make and very cheap. All you need to do is:
1. Go shell finding at the beach. Doesn't sound too hard right? Well we ended up going to 4 different beaches to get biggish size ones. Collect different shapes and sizes to make your crab collection fun!
2. Eyes and legs. Head on down to your local cheap store or craft store and pick up some eyes and felt. For the legs, we did a design of a diamond on a rectangle. The long rectangle is glued under the shell, while you cut the diamond in to little legs.
3. Put him/her together. Glue on the eyes, glue on the legs and presto! you have your own little shell crab family.
If you wanted to be more crafty or exciting, give each one a personality. Maybe one with crazy hair, one with glasses, one with a moustache etc. Kids will love the fact they made them and will be entertained playing with their little crab family :)
