I just finished one. I used 24' blocks and put the bibs on the block & sewed just on the inside of the bib binding. Sometimes I did straight stitching and sometimes decorative stitching. I used variegated thread on top. I used a muslin base and you do not want a heavy batting as the bibs are heavy to begin with. If I did it again I would use flannel as my batting. Live and learn. I used muslin base and stitched everything to warm and natural, way to heavy so I went back and cut away the warm and natural where it was not sewn down. I did not do it the traditional style with the back sewn with the top but did a sew and flip type back and tied with pearl cotton in between the bibs. If I can get my son to down load the pictures I just took I will post them. If this doesn't make sense and you have questions please feel free to pm me and I will be happy to answer them. I am not always good at explaining in writing.
