Double-thick crochet stitch: LOVE this technique! Demonstrated to make thick hot pads but I'm making an ear warmer band, and am thinking about using it to make kennel pads for bigger dogs (that need more padding).
Miss Abigail's Hope Chest: Favorite Crocheted Hot Pads I have been making these for years--they are great. These directions solve problem of uneven edges and a better way to finish off the last row. I usually add a row of sc or reverse sc (crab stitch) around the finished potholder just for a special trim.
