I use it for embroidery all the time. Well not each and every time, but lots. I just put a few drops on 4 sides of the top of the spool and let it drip/soak. then I touch my finger to the tip of the bottle and run my finger down the needle. I feel it gives the little bit of help that I need when things just aren't going smoothly. My friend has a 4 needle machine and she used more! Linda
