i used a selection of odd bits of wool and threads, i started off in the middle and used the first thread to make the curved shape and them ever thing else followed after, changing shape as i went. the process is a bit like woven tapestry as you actually work from the back, so you dont know what it is going to look like until it is finished and off the 'loom'.
when it was finished i backed it with vylene to hold it all together.
a couple of things i would have done differently is not use the onange weft threads and maybe make the sky a bit smaller and try and keep the edges a bit more even, this is difficult because the threads are all different thicknesses..... still next time !!!
