Thanks for the compliments!

Do you piece using a machine? I'm giving that a go for the first time and can't get my seams to form points at all.
Well, not that my piecing is always perfect (those pinwheels were hard), but I think there are a few things to make sure everything lines up nicely. (I do use a machine, but I have also done by hand. It is easier to get more precise piecing by hand, but it takes SO much longer and I would rather have a few mistakes on the machine. I can live with that! )
-Use a rotary cutter and make sure all of your pieces are the correct size (even 1/8 inch will throw things off)
-Use a lot of pins to help keep everything lined up. When you are joining up seams put the pin right through both seams.
like this-Sew slowly-the faster you go, the less likely your seams will match up.
-Check all of the settings on your machine-There is a knob on mine that adjusts the presser foot. If the pressure is too much it can cause your layers to shift.
Thats all I can think of for now-hope that helps
