Perler beads items (Palm Harbor CR 1 Tpa Road)

Any perler beads, boards, tweezers, patterns, grandson just discovered these and loves them, I was going to order a kit but they only come with 1 board and I hope to have enough supplies to let him and a friend or two play with them when he visits me, without spending a ton of money on something he might not be interested in long term. thank you - I pick up promptly!
