I'm like Feline Fanatic--I like the BeGone blue marker and would add that if you quilt somewhere that gets lots of sunlight to not leave it sitting. I also like those purple air erase too.

I suggest you not use press & seal as a "tracing paper"--it's a bear to get to peel off if your stitching is fairly tight.
Also make sure to check that your thread doesn't absorb any marker and hold the color--I had that problem with Crayola markers once with a poly thread.

Thanks for the warning - I wouldn’t have thought of that possibility.

I would use freezer paper, not wax paper- wax paper can leave residue behind ( wax- that can be difficult to remove) I made that mistake once. Freezer paper the shiny side irons onto the fabric with no residue. I use freezer paper in my sewing room almost every day- much more than in the kitchen. :)

Crayola Ultra Washable markers
 

Ditto on the Crayola Ultra Washable markers. Not only do they work nicely, but they're relatively inexpensive and come in a variety of colors. I love 'em. Presently, I'm marking out a quite intricate quilting motif on plain, pure white and doing so without any trepidation. If it's a small item, I simply spray with a good mist of cold water and wipe the area. However, I do wash all my quilts when they're finally bound, usually in cold water, and then warm dry and fluff. I've never had a problem and finally got rid of my drawer full of items that didn't really work.

You'll love them.

Freezer paper isn’t used in UK kitchens - I’ve never seen it on sale in a supermarket here. An American friend who came to stay was very puzzled when that was what I asked her to bring me! You can buy it at quilt shows, luckily.

Thats very good to know - thankyou. I’ll see if I can find a UK supplier.

If you use tissue paper or tracing paper, make sure your stitches are small so it will tear away easily! I’ve had to use a tweezer to pick out remaining paper bits...

If you are going to be washing the WHing after it is done, I would suggest Crayola Washable Markers. Experience proves every color washes out, they work.

I just did some ovals on a white border, marked mine with a plastic Hera marker.

That’s happened to me when paper-piecing!
