SULKY Cotton Blendables is a 30 wt cotton thread created for quilting and decorative stitching where gentle colour changes add visual interest. The Thimbleberries “Flying Colours” collection includes ten coordinated spools in a curated palette that complements classic quilt fabrics and tonal projects. Use it when you want blended shading without frequent thread changes, and stitch a quick sample to see how the colour transitions read on your fabric.
