Darning Filling Stitch
Cut and wrap the bars (Fig. A). Bring needle up in center space and “darn” each corner intersection separately. Pass the needle over the first bar going right, under the second bar, over the third and under the fourth. Now go in reverse direction by passing the needle over the fourth, under the third, over the second and under the first. Reverse and go over the first, under the second, etc. Repeat until size desired is reached. Wind thread around wrapped bar to next junction and work the second corner (Fig. B). When all corners are completed, place a center web (Fig. C). Work needle to outside block row and finish.
