Clean the chair with paint surface cleaner and sand away any unevenness, if necessary.
Paint the chair using a matte furniture paint. Let dry, and if you like, apply another coat of paint if the coverage is inadequate. Let the chair dry for about 2 days.
Use a staple gun to staple one end of the yarn to the underside of the lower edge of the seat, about 5 cm from the left edge. Wrap the yarn around the entire seat from underneath and up, until only 5 cm remain to the right edge. Trim the yarn and staple the end to the underside of the seat.
Make a shuttle for weaving: Cut out an approximately 30 x 2 cm piece of sturdy cardboard. Make a score at the top and bottom of the short sides.
Attach a new yarn end to the underside of the left edge of the seat, about 5 cm from the top edge, and wrap a bit of yarn onto the cardboard shuttle.
Weave as follows: Using the shuttle, weave the yarn from the left edge to the right edge, under two pieces of yarn and over two pieces of yarn, all the way to the other side. Wrap the yarn underneath and begin the next round from the left again. For each new round, shift the weaving by one piece of yarn, to create a woven checked pattern. Once you have woven the entire seat, attach the yarn to the underside of the seat with a staple gun.
Weave the backrest the same way as the seat. First, wrap the piece of yarn from the underside and up, and then weave from left to right. Just remember that you have to weave both the front and back of the backrest.
Do you want to give a little love to an old, worn-out wooden chair? Spruce it up with paint and thick yarn woven into a lovely checked pattern. Reusing items you already own to make something new is fun and eco-friendly. Try things out as you go; if you aren't quite satisfied, just pull up the yarn and start over.
