Thank you for that..... have a look at "G"... where the black zig zag lines are I have coloured patterned material... one line zig zagged from top to bottom.... the next line facing opposite way, zig zagged from top to bottom, the third one facing the same as the first one and the fourth one facing the same way as the second one.... now I have to go back to look at the name...... not my day today.... I couldn't find out where I had been and had to come back to this site......
