Lots of good tips and some that I will use. Especially slowing down as I am more like my friend that calls herself a "slap dash" quilter. But it doesn't bother her.
I want to do the Harriet Hargrave exercises. Have not tired the Sally ones but will be on the look out for that book.
Only new thing I can add is the size of your pins. Invest in some silk pins, they have a thinner shaft and distort the fabric less where you are pinning.
