My 6yr old is obessed with looming.
Definitely get the rainbow loom board. Toys r us & big w sell them as well.
For the looms the cheaper ones do my daughter fine but she only does the easier bracelets so i get her 12 packs for $10 for myself I get the rainbow loom ones. I do a lot of charms & harder bracelets & the cheap looms either break under the tension or stretch so much my chsrms lose their shape.
I also like the metal rainbow hook much better than the plastic ones.
