Welcome to the Quilting Board!
I really like your quilt, Tink.
It will be quite a while, since I've just started doing my hexis as a train project (while riding), but I've been watching your progress as I too was wondering how I was going to finish this off when it gets to that point (LOL probably years from now).
That looks like alot of work - but very worth it in the end - its going to be a beauty.
You're work is supurb! I have enjoyed following the progress on your quilt.
I have been following your quilt thank you for posting the steps you have done an amazing job!
It's really pretty! Love your colors!
I am working on my GFG too....I have most of the flowers ready and am now working on sewing on the sashing hexies....
My thought on the ones along the top and botttom : For the "inner" was to create a paper hexie with three normal sides, two longer sides and then another bottom straight side... and then rectangles to get the same length for the "outer" ones in the same length...so that I end up with a straight border. (kind of like your picture but with less extra on the sides...and using some type of shaped paper stabilizer....)
For the sides, I was thinking about the same process as the inner, but two hexie sides and then the rest would end up as a rectangle.... (very much like you did in the first picture on the bottom right)
But I have not mathematically worked it on paper yet. Nor have I thought about the corners.....
But I do like what you are doing with leaving the extra!
It definately would be easier to square it, but I love the wonky shape if left natural-like :-)
I've done a scalloped border with bias binding and it wasn't too bad, but what concerns me on this one would be the number of times you have to stop and turn...and then getting the bias pulled well. I am sure it is doable, but it scares me!
I didn't say it in my other message, but your quilt is gorgeous and gives me hope that some day I will finish mine!
