Thank you. I am more of a knitter than crocheter but I can give it a try, I appreciate it.erlibrd, I measured the swifter duster refill. I cast on 32 chains....sc...and did the loop stitch scattered through the rows. When I got to the length of the swifter refill...I followed the shape of the refill and sewed it together. Then I stitched down the two sides....making space to insert the swifter tool. That is the best I can explain what I did. If you crochet...you may have questions???? or. The loop stitch was new to me. It is a sc and then pick up thread from the other hand...slip off and end the sc. Perhaps you may know the loop stitch or Google it. It is very easy. Questions??
