I also use Maderia embroidery thread except I use the poly. I buy from a company called Allstitch located in Baltimore, Maryland. They provide great service, good prices and carry lots of other embroidery supplies. Their website is www.allstitch.net. They often include free samples of items they carry like stabilizers, etc. I am a Marylander by birth, Harford County, but now live just over the state line in Southern York County, Pa. Good luck, Barb
