Thanks all for the kind words. Glad you like them.
Harwood, I assume you mean the Candy Floss trees.
Ok here goes
You need barbecue bamboo sticks, a small palette knife or a suitable thin spreading knife , expanding foam , a piece of thick wood or foam with loads of 3-4mm holes drilled around 25mm apart & most important of all ,speed i.e. you have to be quick as the foam starts to expand immediately.
Pick up a stick, squirt a small bead of foam on a piece of card or thin mdf ( you can use this for bases etc afterward so no waste )with the palette knife swipe some foam thinly on the stick ( no need to be uniform as the foam spreads in all directions ). Foam starts to stick & elongate in thin threads but this is a good thing as it adds detail.
Place stick upright in the holed wood. Repeat. Do not let the sticks touch.Stop every so often to scrape the cured foam from the knife's blade.
They will harden light yellow indoors or dark yellow in the sun.Wash or paint etc.
This should help but email me if something is not clear.
Much more stuff on my blog
Enjoy
