You'll need a handful of fabric scraps in wintry colours, a piece of felt or some some light quilt wadding, a piece of stabiliser, and a piece of water soluble fabric. Textured and glittery yarns - particularly frosty eyelash yarns - are wonderful for adding texture and detail to the landscape. A few machine threads (white, black, grey and silver), are all you need for the stitching.
I'll show you the frames I use and how to finish and mount your work within them.
