Prescencia Perle Cotton is 100% extra-long staple Egyptian cotton, mercerized for strength, colorfast, bleachfast* and shrinkfast.
One 10-gram ball of size 3 perle cotton has approximately 30 yards of thread. I like to use this thread to make very visible stitches on wool.
Use the chart below to compare the different weights of thread.
* All colors are Bleachfast except 1163, 1166, 3802, 3810, & 3822. These colors are Colorfast but not Bleachfast.
