i use 80 cm. but when doing stitches, I folded 1 strand.......:):):):)
more or less 50 cm
about 50 cm for hardanger and about 35 cm for cross-stitch
I use 50cm except for metallic then 30cm.
usually 36 inches
aproximadamente 50cm:D
About 38-40 cm. If i stitch in 2 strands (or any even number), I measure the thread around elbow (about 78-80 cm) and fold in two.
About 18" but not more.
Yo uso 12", más o menos 30 cms y me va muy bien.
