Art/craft for 8-9 year olds

[Twatterati]

Need inspiration for niece and nephew’s birthday (9 soon).

Can you suggest some craft activities or art ones that can be done with minimal adult input please. Budget for each is about £30/40 so could get a few cheaper things or one bigger thing.

My neices liked GALT brand sets. I've filtered for 8-10yrs, but some of the suggestions are too young.

They also liked a lipgloss making kit and bath bomb kit.

Thanks @7238SM☺️

Hama beads are very popular here. They'll need an adult to iron them once they're done, but still provides hours of adult-free entertainment while they make them.

I was also going to suggest galt or even baker ross
