Keep in mind this is for small repairs of course.
If there's a huge rip, move on and buy another.
Step 2: Supplies
Ball-Point Sewing Needle FOR KNITS
(you'll know if you test it gently and it doesn't prick your finger as much as a Sharp needle)
Thread Clipper (or small scissor for control)
Wooly nylon thread comes in a limited range of colors so there's a high chance
that you will not get the exact color. Get a color thats similar or close to the color of your stockings.
The stitches are so small it won't be noticed.
My fishnets were magenta colored but I used the purple grape thread.
The thread itself is pretty pricey too so it might not be practical to do this unless you know someone who uses woolly nylon thread for serging and sewing.
If you own a lot of fishnets, especially in one color (like black), then it is worth it getting the thread.
Save your eyes, time, and sanity. Use a needle threader.
Don't use a regular needle for knits, it can ruin or shred the fibers.
