Joy... I suffer from this too, the fear of quilting. You go into the room, see your beautiful fabric sitting next to your machine, pristine and untouched... next to it are your mat and rotary cutter and they look back at you and try to stare you down. So you slowly back out of the room and put the kettle on, run the hoover round and then it starts to get dark and you really should not start a project that late in the day. So you close the door.
You can start again in the morning, when you have all day to take a run at it. But when you walk in the fabric looks so untainted and then you start to think what if I end up measuring once and then have to cut twice... what about the waste. Then you realise that the quilt poilice are in in the neighbourhood... watching through the window. Best leave it.
This goes on for days, then one day, when you least expect it, the rebel quilter awakes. She marches to the machine, switches it on and with the gently stroke of her hand shows who is in charge. The fabric races to lie down on the mat ready to be transformed. The hand shakes a little and then you start but before you know it, you have nearly finished the top and start wondering what took you so long.
I am glad to see you are channelling your inner rebel quilter and am sure that the quilt will be marvelous.
