The full palette of Isacord thread is in this collection, plus some of the discontinued colors. BERNINA Small, Medium and Oval Hoop files with Cutwork are prearranged with "blanks" and cutwork steps, ready for you to pop in the colors you wish "chip-stitch".
 
Thread color numbers are embeded in each chip, along with buttonhole openings. If you don't yet have the BERNINA Cutwork tool, scissors will work too.
