When I first read this thread, I thought, "Oh, I can give her some advice", but guess what? Everyone else said everything and more than what I was going to say! Take it all into consideration. All of us are here to help each other and that includes you. Every one of us started out at some point not knowing how to do ANYTHING, but we learned that it all starts with sewing 2 pieces of fabric together. If the seam is not straight, try it again. Who will know? Who will care? Tape a piece of masking tape on your machine to show you where the 1/4" mark is and try it again, and again, and again. Practice, practice. Before long, you will have DONE it, you'll feel so accomplished that you will have the incentive to go on. It builds upon itself. When I started, there were no computers, I didn't know anyone who quilted, there were no classes (or I couldn't afford them), so I went to a fabric store and bought an inexpensive book on beginner quilting, and a couple quarter-yard lengths of fabric (there were no fat quarters then, either). I didn't even buy batting because I was so unsure about doing this thing, and besides, what would I do with it if this didn't work out? So it was me, the book, and my machine (which only sewed straight stitches and zigzag stitches). I just went step by step, over and over, and guess what - I LEARNED! Than I bought a little flannel to use for batting. Then I attempted a small project (potholder) which was not perfect, but I finished it! I was a quilter! That how it started.
Just come back to this board with your questions or problems. We've all had the same questions and problems and we will help you. There's nothing too unimportant to ask. Good luck. We're looking forward to hearing from you and the progress you're making!
