Four little hand poured organic beeswax 'doughnuts', nestled in black cotton in a black Stitchsperation tin.
Run your embroidery floss through one of your 'doughnuts' to coat it and then run the thread through your fingers a few times to remove any excess. This will help your floss glide through your fabric and help reduce the amount of knots and snags. This isn't always necessary but can help when stitching with metallic threads or anything that gets knotted easily.
I've been using this for the last few months and love it!
Also beeswax is better for your thread than thread conditioners made from silicones and other synthetic substances. Yay Bees!
