Hi,
Thanks for your comments guys !
Manuelke : hte leaves come from Hudson&Allen. Originally they are birch tree seeds, so you can pick them in the nature if you have the chance to have a birch tree next to your house. For for a reasonable price Hudson and Allen give a fair amount of natural or tinted leaves.
Plus models does PE colored leaves. But they are rather expensive for the number you have in the box..It would have cost me a lot if I choosed this kind of leaves...
And yes th tree is home made. I didn't took picture of the construction phasis, but basically you put togehther iron wire, cut them at the top and place each branch like when you peel a banana. put your putty all around and on the branch, make streaks to reproduce the trunk, paint it and after that glue nice piece of asparagus on each branch and that's it. My tree look odd at the top of it as I run out of asparagus at the end of the process. And don't worry, my english is not better than yours...
Claude : to dry or not to dry, that's the question

! I made a test, letting dry one branch of aparagus. You may find it on the second picture, far right of the tree, thin and less greenish than the rest. I let it dry, use hair spray to conserv it. The problem is that branch looks now stunted and dwarfed. i advise you to airbrush your branch just after cutting them. the acrylic will have the hairspray function. If your branch turn lighter, airbrush it again with a very thin "tête". At last, it's amazing all the small flowers you can find for modelling for reasonnable price.
Best,
Julien
