As I said before I really love freeform work.
I once even wrote a tutorial on freeform bead embroidery (in german).
First I show how to embroider beads (with explaining pictures).
Then I tell how to encase a piece of cardboard with your fabric to use as cheap alternative for an embroidery hoop (with explaining pictures too).
And in the end I show how to begin with your freeform embroidery (which for me is always the most difficult part) (with explaining pictures too).
The item on the picture is a bead embroidered button I once made.
