I have used the eye of a darning needle when I have rolled flowers which also works. I noticed in the gallery that MFT is the most used flower die cut there. Today I was in mikes and Spellbinders have two identical die cuts as MFT only larger. One looks like the rose and the other looked like a mum or daisy.
I have not noticed anyone mentioning Spellbinders as thier die cut of choice, i wonder if it is because they look like they are much larger. Also saw a video of Tim Holtz which is another version using what they referred to as a pinecone diecut made with felt made into a rose..
