Dyed example: 28ct monaco & 28ct lugana
Colors in the group photo are most accurate. DMC floss is used to show color family equivalent. This does not mean that they're an exact match, just a reference.
Linen will always dye darker/more vibrant than any cross stitch fabric, then aida (14ct darkest, 20ct, 16ct, & 18ct dyeing lightest), followed by evenweave fabrics (usually not 100% natural fiber) dyeing the lightest. All opals will dye about 10% lighter because of the opalescent thread woven through it.
Sizes are prior to dyeing. There will be some shrinkage during the dyeing process.
