I love how our brains can see what we can't. Just made a spring/Easter twisted table runner. 14 rows to fit my 72 inch table. Top was done, but no mojo to sandwich and quilt. I told my DH it just "bothers" me. Finally sandwiched it, and was ready to quilt. Picked it up, and there it was...row 13 had one HST turned the wrong way! Able to take it apart, re-sew, and finish it up. Looked at it for days, and it just did not compute!
