Whenever I use elements that have a finished edge, I like to nail them down with some invisible stitching well inside that edge, once I'm sure of where they need to be. That way, I can tuck things under that edge. I drag these projects around with me like a toddler does a blankie so, at this stage, my stitching is all about construction.
This piece is already feeling not big enough. I have more of the dark linen background, but I need a good sized piece of black polar fleece to built the whole thing on - adding on as design demands.
I stumbled back through the archives to find a few old tricks, ways of making the cloth and the thread see sense, work together in more than just a construction manner.
