Lacy blues: Here is a photo of the hen saddle/sweater without a chicken in it. Keep in mind that its been washed and didn't dry flat unfortunately and so the little wing slits are kind of rolled and twisted up a bit. I just basically used the general shape of the pattern they used on the initial pages of this thread. and then cut 2 inch slots along the area where the wing would be situated leaving a 3/4 inch margin from the edges.
