Aurifil threads are a personal favorite machine thread —they're known for their quality and come in a rainbow of colors we carry 100 colours each of 40wt and 50wt, and are happy to order in the thread colours that you need - we have thread samples for the entire collection, and a rich selection of 28wt and 12wt as well. Whether you're piecing together a quilt top using 50wt or adding those final hand stitching touches with 6 strand floss, Aurifil's wool and cotton threads are a dream to work with. They glide smoothly and hold up beautifully, ensuring your quilt stays strong and stunning for years to come.
