I was doing a pattern where I needed to sew together jelly roll strips and with my lack of sleep I forgot to take out the pieces for the borders and in between the blocks. I instead sewed ALL of the strips together.
This is going to take me FOREVER!! I was so happy when I sewed the last set together and about 30 seconds later had an OMG what did I do moment. I was adjusting to take it from a twin to king as well so I need to rip the stitches out of about 40 sets of strips. I know it was from the lack of sleep but this is the biggest mistake I have made so far in my quilting "career" Oh man!!! :*(
