What You'll Need
Warping: Using the direct, peg warping method, alternate colors in each slot while warping. That is, sley all of the Grey yarns first, threading a slot, skipping a slot and so on. After all of the Grey yarns are threaded, fill in the empty slots with Geranium. Wind the warp onto the back beam and then thread the adjacent holes. Your color order will be 2 Grey, 2 Geranium, repeat.
Weaving: Alternate 2 ends of Grey and 2 ends of Geranium, repeat, just as you did in the warp. Weave a balanced weave which means that you will see a square space (not a rectangle space or lack of space) between the intersection of the warp and weft threads. This will ensure that the houndstooth pattern will be balanced warp-wise and weft-wise.
Finishing: To secure the weft for washing, knot the warp yarns in groups of 4 on both ends of the weaving. Wash in hot water with soap, rinse in cool water with a 1/2 cup of vinegar, and then rinse in clean water for 15 minute each. Put the fabric in the dryer with a few towels on medium heat for 15 minutes, checking frequently. Lay flat to dry.
Assembly: Wrap the fabric around the 16”x16” square pillow form. To measure, start with a knotted end and place it in the middle of the pillow. Then wrap the fabric all the way around the pillow form, past the knotted end and to the edge of the pillow form (like an envelope). Mark this end at the edge of the pillow and sew a couple of zigzag lines across at this point. (You can also serge this line.) Turn over the zigzag end and hand sew a 1/2" hem. Lay the fabric flat with the right wide up (hem down) and fold it in an envelope with the knotted side first and the right side of the hem meeting the edge of the pillow. Single crochet or stitch up the sides and turn right side out.
