I have very little experience with hand quilting and I want to improve. I have put together a simple top using rectangles. I was planning to mark the blocks with a simple leaf design and use this to practice my hand quilting. I am sooo frustrated with trying to mark the stencil. I have tried several marking pencils and they seem so difficult. Either they don't show up or the lead breaks. I have used several colors. Does anyone have any advice on better pencils or method? Thanks!
