1) Organize: Gather the materials you need, make sure you have enough for everyone, and clear away any unwanted clutter.
2) Reduce choices: Cultivating creativity in others can be a tricky matter. Learning a skill, and exercising your creative ideas both have a time and a place. If I am teaching someone a new skill, I reduce most choices they need to make (i.e. shape, size, materials) which helps them focus they’re attention to the skill at hand. If I want to allow more creative freedom, I will open up the range of choices, but reduce the need of new skills.
3) Know what you’re doing: Is this obvious? I have tried teaching something I don’t know well enough and it doesn’t go over so good. But I have also learned that even if I know how to do something well, sometimes I need to practice how to show someone else this skill. Finding tutorials on your subject can be a great help!
4) Plan for fun not perfection: When I have kids over to do some crafting, my main goal is for them to enjoy what they are doing. I try to not focus on the end product as much as the process itself. I also modify the skills needed, and lend a helping hand when necessary to produce a product the kid can be satisfied with and also proud of. Often, the kids want to play with the materials in other ways than what we’ve planned for, and that’s great! Let them! Whether they end up with a god’s eye or a raft for the bath tub really doesn’t matter in the end. You may just have a genius on your hands.
