I have had my share of bad sewing/quilting bad habits. You would think after more than 4 decades of sewing/quilting I could stop doing some of them.
My worst habit , is yes ...... I do sew over pins ( not all the time). Thankfully I have slowed down my machine when I do this , and no damage has been done. But I can still hear my Mom yelling at me , STOP sewing over PINS!
So fess up .... whats your bad habit, one you really wish you could break?
