Ok, so I will probably starch the half square triangles and then not on the squares. I am not worried about dyes transfering on this quilt since everything is Easter Egg color (pastel purples, yellows, pinks and greens)and I always wash a quilt before using it. I will test my blue washout marker on all the quilts since I am not sure how the sizing will react with it. Usually that is done by putting a blue mark on a scrap of each fabric during construction. Then I soak then in cold water before marking the whole quilt. I haven't ever had a fabric be stained, but I always check just in case since the label on the pens tells me to.
