This is a great thread -- lots of smiles
Tuckyquilter, I too use the French seam for my pillow cases -- as my Mother and Grandmother did before me (I can't remember when I made my first pillow case -- they started me early). I still see flat felled seams in jeans -- usually the outside leg seam and the center back seam.
Wildyard, I hear you about the ugly feed sacks -- my quilting Grandma made me lots of clothes from feed sacks that I thought were gastly. Interestingly, she made me a quilt out of the left overs from the clothes she made me from feed sacks and I have to say the fabrics look much better in the quilt.
