Oh that's a very cool idea! Most crafts (if you have an idea that is) you can find some sort of tutorial somewhere probably, or something similar that you can use for your own design.. I always browse endlessly through other crafts before I decide what I will create.. and then often first collect the items needed and adjust it a bit lol.
But something with lights or movement in it for Halloween or Christmas, I say go for it, give it a try! You might design something people love and worth selling :)
This sounds very interesting.
You have just given me a seasonal business idea. 😊
Awesome, looks like we will both be crafting for some small business around the holidays :)
