That\'s wierd... I was trying to work this out last week!
Here\'s what I ended up with after an afternoon of experimenting:
These are correct to scale for large open roses at 28mm scale, ie: about 3 - 4mm diameter.
Having tried sculpting them from a blob of solid greenstuff, which was a nightmare, I eventually settled on this technique:
I first found a piece of stiff wire which would become the stalk of the rose... I cut it far longer than I needed the finished article, at least an inch long.
I then rolled out a really thin sheet of greenstuff, like 0.5mm or less thick. I then cut that into narrow strips, about 2mm to 3mm wide... and then cut those strips to about 15 - 20mm long.
I tacked the end of the strip onto the end of the wire, as if it were a pennant flying from the end of the wire... I used cyanoacrolate to hold it in place (a tiny bit).
I then gently wound the strip around the end of the wire, spiralling downwards slightly so that the lower edge of it was about 1/2 a mm below the end of the wire.
Finally, I blended the end of the strip into the layer below, and then rounded off the underneath where it joins the wire beneath the flower.... Then I teased out the petals to a point, spiralling in towards the center, and in between each of the petals, pushed little indentations in to give seperation to the petals... all this sculpting was done with the tip of a fine scalpel blade.
After they were set I then finished off the flowers by adding tiny paper leaves to the stalks, and made some teensy little thorns and tacked those in place with very thin Cyano.
I\'m pretty happy with how they came out, certainly from a few inches away I think they look like roses... and I haven\'t tried painting them yet.
Obviously they don\'t have to be growing out of a skulls mouth, but it helps
I was going to write a little tutorial on this with pics, but haven\'t got round to it yet :-(
