Mettler Thread is for creative and novelty. The Art. 259 is excellent thread in solid colors for decorative seams. The Art. 240 and Art. 9240 are for regular fine and sewing.
Art. 240 - 219 yds. | Art. 259 - 219 yds. | Art. 9240 - 220 yds.
The key below is useful in knowing which thread colors on the color chart are available in certain sizes. For example, the color Dark Apricot (#0592 on the color chart) would be available in sizes 240 and 259, but not in size 248. The variegated colors can be found at the bottom right corner of the color chart. Even though there maybe dots besides the color, we may not carry its size.
