Having blocked some red sinamay on it, I stitched brim reed and bias sinamay to the edge, added a red ribbon covered head band...and then went festive!
I recently posted on facebook that I make my own blocking springs (saves all that pinning and string!), this is how they are used
and this is what I use to make them, red hollow polythene belting, sometimes called red quick go, or hollow poly tubing. I use 8mm diameter, and use these tiny metal connectors that push into either end. Bear in mind once in, they can't be removed. If you intend trying it out, cut your tubing slightly smaller than you need as it will stretch, and you do want a good tight fit.
