I use the wing needle quite often to make an edge around embroidered cloths before doing the crochet boder. My machine has some lovely stitches which are very effective for the wing needle when doing decorative stitching on soft furnishings like lamp shades. I also have a double needle which contains one straight and one wing needle which is used for some decorative stitching. When my triplet girls were small I used a lot of the stitching on their clothes - now I'll have to wait until one day for grand children!
