Hand Embroidery : Edging Stitch - Randa Embroidery - Needle Lace - Blanket Stitch Variation 

I am sorry for late reply, my friend I am using embroidery threads,these are called Dmc embroidery thread and Anchor embroidery thread, these two brands are very common to use for embroidery, but for edging if you want you can use Crochet thread as well which should be thick in texture not thin. Thanks
