Create Your Own Gacha Series

What can we use if we can't find plastic capsules or cardstock for the character pieces and collector cards?

If capsules are unavailable, use small resealable snack bags or empty pill containers and for cardstock cut thick printer paper, index cards, or thin cereal-box cardboard to the same size as in the 'Cut cardstock rectangles sized to fit inside your capsules' step so the character pieces and collector cards still fit when you 'place one character piece and its matching card into a capsule and close it'.

My cut characters are too big or my marker colors keep smudging—how do I fix those problems?

Double-check the dimensions before you cut by comparing scrap paper sketches to the capsule opening, trim edges after you 'Carefully cut out each colored character', use fine-tipped permanent markers or let marker and glue fully dry and consider sealing cards with clear tape so colors won't smudge when you 'shuffle all the closed capsules to mix the rarities'.

How can I adapt this activity for younger kids or make it more challenging for older kids?

For younger kids, reduce to 4 characters, pre-cut the 'cardstock rectangles' and let them color and stick stickers, while older kids can expand to more than eight characters, assign numerical rarity percentages when they 'Give each chosen character a rarity level', design laminated collector cards and create trading rules or series variants.

What are some fun ways to personalize or extend our finished gacha series after packing the capsules?

Enhance your series by laminating the collector cards, adding serial numbers or foil accents to rarer characters, creating themed blind-pack wrappers to 'shuffle all the closed capsules', and posting photos plus a series description to DIY.org as suggested in the instructions.
