Robert Kaufman "Shetland Flannel" SRKF-13936-9 Navy
Two lengths available; 1st is 1.75 yds and 2nd is 3.50 yds. The piece that is 1.75 yds is a different dye lot so is slightly darker than the 3.5 yd piece.
A dark blue flannel, you have to look really closely to see the chevron design. It provides some great rich color, but subtle movement. Great for both rag quilts and traditional flannel quilts, this is a woven flannel.
