DD is 17 & has been through many stages, hobbies and pastimes, some of the skills I have picked up include:
Dinghy sailing & launching & unfortunately Dinghy repair & maintenance
I always made soft furnishings but now I can make full circle skirts almost without thought, stick crystals, sequins and motifs just about anywhere!! Using all sorts of fabrics including georgette & lycra
My 8 times table is amazing!
I read sheet music enough to follow a tune, cut & alter it sensibly for a singer and judge the range of the singer needed to sing a piece.
I can cut, edit & mix tracks
I can edit video and add music so it looks good
I can almost style afro hair!! (less successfully than most other stuff)
& now I need to learn to be a driving instructor
So what 'odd' skills, have you picked up?
