When is the last time you fixed a hole in your sock? I remember learning to darn socks with Grandma and decided to re-learn the skill. Darning socks is easy if it is a small hole but one still needs to remember that this seam will be on the foot so if you make the seam to big it will be uncomfortable. When darning socks, you will need a darning egg or something like it. If you don’t have a darning egg, use a baseball or plastic Easter egg. I have read that people use lemons or tennis balls instead of a darning tool but I do not like those suggestions. When using a tennis ball, I can see the thread getting connected to the fuzz on the tennis ball and could cause issues. And using a lemon could get messy if you stab the fruit. Something smooth and rounded is needed, like a light bulb. Darning a large hole in a sock it is best to use the woven repair method. It takes practice but works well.
