Helping kids learn rainbow loom

So today Wednesday instead of school, my parents had me help teach kids at Selva Negra how to do Rainbow loom bracelets. So I went to a house with two girls who I am guessing are around ten. My grandma (the owner of the farm) drove me to the house and introduced me to the girls. We sat down and I showed them who to do a single the easiest one. Then I passed the loom to one of the girls and had her do it. She had obviously been paying attention because she caught on fast and did the bracelet super quick. Then she passed it to her sister who also finished very fast. So I decided to give them something harder. For the record I only know two different designs and they are the two easiest. So I showed them the harder design and they mastered it really fast and the first thing I think is what else do  I show them? So I try to sow them another design but that just falls apart. So I just have them keep working on the harder one until my grandma comes to pick me up. Then I chatted with my relatives in the car until my grandma drops me off. Then I  walked to my house and wrote this but that was kind of self explanatory. I took pictures and I couldn't get them off the phone and it was really dark where I was so no pictures till I can get my dad to help me.
