There are several very good videos on youtube that are great for making a standard size pillowcase with french seams and absolutely ZERO loose threads on the inside. I've seen 3 different videos each giving different measurements. My favorite is using 23" for the body and 13" for the cuff. From start to finish, it shouldn't take you more than 30 minutes to go from raw fabric to a completed beautiful pillow case. These would make great little gifts at Christmas time, if you don't know what to buy someone. Total cost is about $8-$10 depending on the fabric you buy.
