If you are thinking of participating in the Embroiderer's Guild members' challenge, the Guild has a Pinterest board of inspiration pictures. You can have a look here. Some lovely images even if you aren't entering this time!
If you watch Sky Arts Landscape and Portrait Artist of the Year you will have seen Moy Mackay and her felted landscape. We will ignore the reference to craft that crept in -it doesn't seem to apply to any other form of art! Anyway they are actively encouraging embroiderers to be involved. If you fancy having a go and possibly being on the telly, you can find information here.
