This is my quilt Hugs and Kisses, made just with Xs and Os. I actually hadn't intended it to look like this - I'd also made the words "I love you" and was planning on saying something else as well. I think. But when I put some of the Xs and Os together I was amazed at how graphic and pow they looked, so changed the direction I was going.
I made loads of them of varying sizes before starting to sew them together - and all of them didn't make it into the quilt. For this quilt I didn't add any extra background fabric to make any letter fit, I just whacked off anything that stuck out. I quilted fans around the border in black perle cotton and outlined each of the letters in varying colors of perle or floss. I shouldn't say outlined the letters. I quilted a bit in from the edge - through all the layers. I could do that using a huge needle - wouldn't want to try it with a baby quilting between needle.
