When I want to mark quilting designs on my fabric, I absolutely LOVE the Bohin mechanical marking pencil. The “lead” available for the pencil is made of a waxy chalk. It adheres to the fabric long enough to quilt the design, but it is easy to remove when you are finished quilting. The mechanical pencil includes an eraser which actually works to remove the chalk if you make a mistake or change your mind. The chalk refills come in several colors; I know these colors are available—white, gray, green, and yellow (there may be more). This pencil is very easy to mark with making a nice thin (0.9 mm), smooth line on the fabric. The Bohin mechanical pencil costs around $12 with refills costing around $6. The only con I have found is that when the lead gets to be about 1/2 inch long, the pencil won't mark. You can't keep the lead from pushing back up into the barrel when you try to make a mark. I think this is a big waste of lead, and it is very annoying. I'm hoping new models will correct this problem.
I often use the tulle method of marking a design onto my quilt. (Check out my "Tutorials" page. You'll find out how to use tulle to mark a quilt there.) I find the Bohin mechanical pencil is a bit hard to use when marking through the tulle. The tulle tends to break the “lead” in the Bohin marker. For transferring a quilting design using tulle, I like to use the Allary Chalk Cartridge holder. The Allary Chalk Cartridge Set comes with a plastic case which holds eight white refill "leads" and one in each of the following eight colors: flesh, orange, fuchsia, turquoise, green, violet, medium blue and yellow. The holder mechanism and sharpener are included. The cost for this set is between $9-$12. The “leads” for this holder are thicker and make a wider line than that made by the Bohin, and the “lead” point doesn’t last nearly as long as with the Bohin mechanical pencil. However, I find that the “lead” in this marker holds up much better when used in conjunction with the tulle. There are refill packs available for this holder also. The refill includes a plastic case and 16 “leads” (same as in the original set) and costs approximately $7.
