Decades ago I knited the cardigan for my husband (how young we were in those days!), and then on a cold winter day he leant against a hot stove and the cardigans back was burnt. Recently I found it in the storage, felt its softness, sliped into it and was surprised how good it fitted my present figure
The ugly yellowish patch had to be concealed. I made it this way.
It took some hours but the result payed it.
