Is the type of sewing machine that is controlled by hand?
A manual sewing machine is one that is hand cranked, like an old Singer 99. There’s no foot treadle, no power, just the use of your hands to crank the wheel and guide the fabric.
Should you sew left to right or right to left?
Unless otherwise specified, sew from right to left if you’re right-handed and from left to right if you’re left-handed.
