    I need to cut a 41 inch fabric circle. Has anyone done this and it there an easy way to do it. My understanding is to fold a square one inch larger (or 42in) in quarters and then round it off but I'm not sure how to make sure it will end up to be 41 inches. Would appreciate any suggestions. thanks.

    Your radius would be 20.5 inches, so you could have a string that length, one end tacked to a cork board, the other with a marker through a loop, and scribe your circle using the string as a compass.

    wrap string around pencil,tie, wrap string around pin,stick pin at the corner of all folded edges. String should measure one inch less than the shortest spot on the material. Hold string tight at both ends and swing around from side to side making your cutting line. cut on line

    This is exactly how I do it. Be careful not to stretch the string.

    Unlike string, dental floss doesn't stretch.

    Cutting large size squares and circles are harder for me then the tiny ones. It took me forever to cut a 40" square.

    Oooh. I thought of another way to do it. You could fold a large piece of paper (bigger than 41 inches) in quarters, then place the center point on the floor under a hinged door so that the paper is directly under the door, with the center aligned to the hinge point of the door. Tape it to the floor, then tape a marker 20.5 inches out on the door and gently open and close the door to scribe the arc. Cut your paper along that line while folded, and theoretically, you will get a nice circle.

    I would probably do this method and find that it does not work as well as the more conventional tack and string way, and so resort to that anyhow.

    But it's fun to think up different ways. Ways that would make my husband and sons shake their heads in mystification. . .
