Keep in mind we want to go for something that isn't too difficult for the child's skill level so trying to build looms that are shaped like our favorite characters would:
- Not allow us to wear them
- Might be too much of a challenge
So sticking to wrist band looms we are left with some options weaving words into the band itself maybe a favorite characters name or something from the Yugioh show itself or the card game. Or we can focus on something like a charm. Looking to the net you could always buy figurines with hooks on them allowing them to be hung and then weave the hooks into the loom bracelet itself. Or another option if the child likes art you could always have them do the art themself on small wooden charms and help them put clips or hooks this way they really have something to show off to friends.
This can be done with anything not just when making Yugioh loom bracelets you could do it with anything like Hello Kitty Loom Bracelets or even Pokemon Loom Bracelets.
