Ha....found this thread by googling "brown pigma pen". I too have made some blocks for the one star project and am trying to comply with the color specified for signing the blocks. I'm having no luck in finding a brown pen and like others worry if I don't "follow" the directions they'll not use the blocks. OY........so guess I'll see if my hubby can run me over the river to michaels. I have done one for each member in my family that served in the military and will put their name and ranks on the blocks. I have 8 ready to go, except the signing.
