Ben,i have used Seafoam, to good effect.There was a good article about this but i can't seem to find it
Now i have to get all this stuff myself, as i will be making a fairly big(ish) dio myself, so here is what i have found
Now this technique works well, but chop it all up small, and go from there, i got too carried away when i did this.......oh and ask in your local florist for the moss.
Now this is actual Bocage, just for reference.....
For seafoam i get mine from here
Got to the bottom, PDI001 is what i got, excellent service too
If you do go with the seafoam, then you will need to get the following
Various herbs(good ones are:tyme, parsley oregano and basil)
Various greens and brown paint, whatever you like
And somewhere to hang them up.
What you need to do is, mix up the PVA with water 50/50 works well.Now put this in the flower sprayer and apply this to the indevidual seafoam peices.Then sprinkle on the herbs to your own taste, then spray again with the PVA mix.Let dry, by hanging them up.Then paint.
Hope this help a bit, email me if you need too
