She said the cooking demonstration with Michael Van de Elzen, a TV foodie sensation and internationally renowned chef, had also been very successful with 80 guests attending.
There had also been a lot of national interest, with people coming from all over New Zealand, Mrs Nelson said.
In general, it had been "wonderful" though the weather had had a big impact, she said.
"I think we could have hoped for better weather."
Rotorua Museum event co-ordinator Kathy Nicholls said the museum did children's arts and crafts every school holidays, and the current ones tied in with the Tulip Festival and two Dutch themed exhibitions on show at the museum.
She said more than 1500 people took part in the crafts and probably more than that for the Dutch-themed school holiday activity trail.
"There's lots of people in town and it's been awesome to see heaps of people out in the gardens, and the tulips look amazing."
Tiari Ashby, 8, took part in windmill and tulip themed arts and crafts at the Rotorua Museum today. She said it was good and she liked getting to colour in.
She said she liked arts and crafts because it was something to do "without annoying our parents".
Manawa Ashby, 7, said the windmills had been fun to colour in but it was hard to fold and make the blades.
