12WT Aurifil 100% cotton threads are ideal for hand-quilting which give a lovely modern or primitive look depending on how you use them. I have personally used these 12WT threads and can recommend their quality myself. They produce a beautiful effect for 'utility stitch' effect for big-stitch hand-quilting. They work as an alternative to stranded pearl embroidery threads and can be used for Sashiko type work as well as cross-stitch using one strand.
