Wing needles have metal flanges on either side of them that push the material out slightly as the needle dips into it. Some machines have decorative stitches that, when combined with the use of a wing needle, can create intricate patterns and borders on your sewing projects. To add crochet edges around baby blankets, use a wing needle to create the base holes around the material without having to spend time punching the holes by hand.
Attach a wing needle to your sewing machine and set it to the zigzag stitch setting, or the longest-running stitch, if your machine does not have a zigzag setting. Do not thread the machine.
Place your blanket under the sewing machine foot so that the first dip of the needle passes through the material, 1/2 inch from the edge.
Run the blanket through the machine so that the needle creates holes in a zigzag pattern, with every other hole 1/2 inch from the edge. Pull the blanket through at a steady pace to ensure the holes are evenly spaced, particularly around the corners.
Crochet around the blanket through every other stitch, passing the thread through the holes that are 1/2 inch from the edge only.
Continue crocheting around the edges to create your desired pattern and bind off.
Choose a crochet thread that matches a color from your blanket for a coordinated look.
