Well I use the yellow ones too. But as I am learning on my third quilt, I didn't use enough, I do have some puckers....OMG
But, I am finishing it and am awaiting Christmas and will ask santa for a long arm machine. I have been quilting the bloody thing for a week and it is stillnot finished.
I should have used more pins. I did get a walking foot which really really helped with the "in the ditch", but so many little squares...ugh.
I love piecing.
