Felted Market Bag and oooops.......Who got the cold shower

Well I put the French Market bag through a hot water wash twice on Thursday night, then 4 more times on Friday morning, I realised on the 2nd wash on Friday that I could just up the wash time on the machine, so the last two washes were for about 20 minutes each before rinsing. It has felted but I don't think it is quite there yet.....DH got home after work and jumped in the shower, well then it happened, someone thumping on the wall, I thought what is that, then realised it was coming from the shower, I went down and asked DH, "is that you banging", he wasn't a very happy chappy, all the hot water was gone, what had I been doing on my day off, well.....I washed my market bag to felt it in hot water, like 4 washes, all with the other clothes etc that needed washing, so it wasn't all wasted.......then son arrived home ready to go out for his birthday, his girlfriend said she had a cold shower also that morning, well I didn't ........so who cares, really...get on with it, as if a cold shower ever hurt anyone...Just because it is the middle of winter. Anyway I really think it needs another go, so I will have to pick my time to give it another hot wash. Probably in the night so the water heats up for the next day. I have pictures but will post later.
