You are not alone. I am sure many others feel this way including me. What I do is use a practice sandwich, and then I do a real "mystic" thing. I close my eyes and envision How I want my arms and hands to move the quilt, I am a free motion gal, and then I dive in. I quilt with music or a book on CD and when I get tired I stop! I know, when I return to the piece my work will not be exactly like how I started but no one and I mean no one but an expert can tell the difference. If the expert is that picky then I don't need their opinion. I continue until finished and the more times I do this the better I get at FM and the less fear I have. Be bold, Be brave and Be the best DM quilter you can BE today. Have fun!
