Wily Textiles adds an item called Fabric, which is crafted from 8 Wool and makes 10 Fabric and your "Can any wool color be dyed?" option thinks the Fabric is the same as Wool, cause it uses the "minecraft:occludes_vibration_signals" tag like Wool, so when crafting a stack of wool into fabric you get a stack+16 fabric, wich when you craft it with dye you get a stack+16 colored wool, wich when crafted into fabric gets you a stack+36 colored fabric, wich are 20 fabric more then the amount you started with

this is the link to my original issue at Wily Textiles: malcolmriley/minecraft-textiles#70

This was fixed in later versions
