I did it. I took a deep breath and started to put the hexagon pouch together. The outer surface and the lining have been cut out, the cord for the drawstring has been measured and cut then finished with hand stitch, running stitch to be precise and the channel for the top, to run the cord through is ready to be pinned into place. Phew. So far so good....no fatal errors. This may not be the way you would put one of these together but if it gets me to my end goal I will be happy however it happens.
There is a still a fair way to go. There's lots of tacking to be done, a label to fit in somewhere and it will all be finished with hand stitch before I remove the tacking. Pins...mustn't forget to pin the edges of the lining before tacking too.
