Hi Captain - great topic.
Your last post kind of touched on what I was going to say. When I've turned up at parties and events with 'pre-made' animals, hats etc, the kids generally tend to take them, run off, and if we're lucky they last 5 minutes - I don't think they really 'get' the piece, it's here and now!
However, the ones that wait and see the item made in front of them more often than not do so with a degree of interest and wonder, and on the whole *seem* to be more connected to the piece, and 'own' the piece more, if you know what I mean. I suppose its a similar thing to the argument that you are more likely to take care of something you have waited for, saved up for, earned, etc than something that is just handed to you. As twisters/modellers, most things are made within the attention span of children ( I have a 5 yr old and a 2 yr old - ok, the 2 yr old isn't the most patient!) but generally speaking they can deal with the wait - and as long as they're interested, will wait, and are pleased with or even cherish the end result then I'm not convinced we live in a world of complete 'instant gratification' and that we have many, many more years of entertaining to come!

Best regards
