No pattern, I'm afraid. I tend to make it up as I go along, I did try but it is really hard writing patterns, much harder than I thought; But if you were interested I could give it a try.
I made one for my friend who has a craft shop. She was wanting something for her shop window and bought a bird cage and asked me if I could make something to go in it.
Apologies for it looking so Monty Python dead parrotish, I wasn't expecting to share this photo. And I don't think it's a Norwegian Blue. ;-)
Well someone saw it and commissioned me to make one for her, so I've made two so she can choose the one she likes best. Hope she likes them.
