I'm left handed for the most basic things: eating, writing and sewing (well yes, sewing is basic to ME :-)). And ironing which is also basic when you sew. Beyond that, the hand I use often depends on who taught me. My right-handed grandmother taught me to knit, so I do that right-handed. My right-handed mother taught me to tie my shoes and a couple of other knots, right-handed. I taught myself to crochet left handed by propping the book up in front of a mirror to follow the diagrams. Recently learning to conduct music it's been a lot of work to teach my right hand to behave, but I've decided to do learn to do it either-handed. Double the practice time and then some!

My father taught me badminton left-handed, and I play it that way still. Broomball- and hockey-handedness was all about best option at the moment, constantly switching if that was most efficient. Tennis I had lessons by a right-handed teacher, so that's more right-handed though I did practise somewhat with both, I didn't want to invest the time to do theme equally well. There are things I appear to do right-handed, like winding wool into balls from a skein, but even though I hold the ball in my left hand and one might assume I wind with my right, I actually hold the right hand still and wind with my left -- Grandmother's influence wasn't total, I guess.

In my pre-teens and early teens I had a medical issue with my left arm and that's the same stretch of time when I learned softball, so I throw and bat mostly righthanded. And poorly.

I play stringed instruments right-handed and have always felt glad to have my co-ordinated hand doing the fretting. My right hand dexterity was nicely developed by piano lessons so to learn various fingerpickings never seemed onerous; that might also be thanks to the teacher who taught me well how to practise and learn things accurately.

Where I really feel left-handed in a right-handed world is with power tools. I use them left-handed, so with a circular saw for example I have to poke my head over at a weird angle to follow a line. Very awkward! Learned early to clamp on a guide when possible. The weedwhacker controls drive me batty. I cannot get comfortable using it right-handed but the controls are counter-intuitive to use left-handed. Since I haven't the budge for left-handed tools I just take my time and pay extra attention to safety. The one power tool where handedness matters little, the vacuum cleaner, is the one tool I prefer to avoid.
