I had read somewhere that you can use freezer paper cut into shapes, iron it onto the quilt, then sew around the outer edges of the freezer paper, then tear the paper off. I'm not sure where I saw this, but I want to try this method. I sometimes use the Golden Threads paper, but when working with a larger block design, it shifts around and tears before I get to finish the block, making my designs a bit uneven. Luckily the fabric is busy and it won't be as noticeable.

The Sulky Solvy is easier to deal with than the cling wrap. It washes out and you don't need to sit there with tweezers after.

My most favorite marking method is Blue Line Eraser. It's awesome!
