I am new to quilting also, I just realized that the charm squares I was cutting will not equal to 10 1/2 in squares, da so I will probably have to add a sash or just chain all the square together. Luckily I am not following a pattern, I just learned to do the "Ohio Star"and I had to frog at least six of the squares till I got it right. Don't give up we are newbies but I know in the future we will get this.
