I just made one up yesterday that I cut from yardage and threw it in front of my kitchen sink so it won't be long and it will need to go in the washing machine. I used a variety of fabrics types, some batiks, some quilt shop quality cottons, and some cheaper cottons, so I'm interested also in how they will all play together when washed. The rug itself came out very flat and needed hardly any pressing. My machine is in quilters dream cabinet and I think that helps much. Also one piece of advice when going around the oval ends in the very beginning, it is important to ease in fullness on the outside round. I needed to do that for at least the first 6 rounds.
