I think everyone has their favorite method of labeling their finished quilts; mine is to cross stitch them.
Here is the label I put on my mom’s quilt:
I use 18-count Aida cloth in either white, antique white, or ivory. I start by charting the words on graph paper, left-justifying the majority of the lines of text. For stitching, a size 26 tapestry needle works best, with two strands of embroidery floss in a color that blends with the fabrics used in the quilt.
How do you label your quilts?
