The first part will involve leaves.
This lovely maple leaf pattern is from Red Heart.
This one is from BellaCrochet and I think it will look nice in a rust colour. The pattern is for a hotpad, but I think I can reduce it's size by using finer yarn and smaller hook.
This one is already Autumnal and is done by Art Threads. I like the contrasting colour of the leaf seam.
This is quite a simple leaf, but will be useful to fill in spaces. The pattern is by Wind Rose Fiber Studio.
I am still on the look out for some oak leaves, so may have to look in some of my books. Hopefully next time I will be able to show some progress.
