HOW TO MAKE AN ARM KNIT POUFFE
long edges. Pull the yarn tail to gather, creating the base of the pouffe, then turn RS out. For the back seam, use the remainder of the yarn tail or cut a new length of yarn and tie to the yarn tail on the inside. With your hands, use mattress stitch to seam the two short edges of the piece. It’s easiest to do this with the RS of the work facing you so you can make sure the seam is invisible – there should be an even three rows of stocking stitch between each purl row all the way around the pouffe.
Place the double fitted sheet inside the arm knitted piece as if putting a bin liner in a bin. Little by little, pour the polystyrene bean bag filling into the sheet, pausing at intervals to reach in and stretch out the sides of the pouffe and push the sheet down to make more room. Once all the beans are in, carefully gather up all the edges of the sheet and tie very firmly with strong twine or thick cotton yarn. Alternatively, if you have a couple of friends on hand to assist you, you may find it easier to have them hold out the sheet while you pour all the beans in before fastening it off and placing it inside the knitted outer.
Make sure any yarn tails are on the inside. For the base of the pouffe, use a length of yarn and your hands to weave a running stitch along the remaining edge. Pull the yarn to gather it together, then tie it off, weaving the end to the inside. Reshape the pouffe to make it plump and round.
