Last night, I pulled my blackwork shirt apart and washed it. I also hot ironed it dry. This gives nice crisp linen and also stops the black thread from bleeding. When I got up this morning and went to the bathroom, one of the sleeves was on the floor. I thought this was a bad thing. When I picked it up, it was wet and on smelling, discovered that my boy cat had been very bad and weed on it!! So before work, I had to wash and dry it again. Luckily, with the cold weather it didn't have time to dry and there was no bleeding.
