We have dark wooden highchairs that I just love. They look like a piece of furniture not a toy, which some of them do. Another thing I like about them is the seat cover. The drawback to them, though, is that they are fabric. They stay clean for about 5 minutes then they have to go back in to the laundry. I was working on another project with vinyl table cloths and came up with this idea. Why not make highchair covers that can be wiped down? Here's how I did it:
Trace the original (above) on a vinyl table cloth. I got a large table cloth on clearance for $3.00. Cut out 2 pieces, front and back. You can use the same table cloth for both sides or make it reversible and use 2 different styles. Cut a coordinating piece for the top using the original as the template. Sew the coordinating piece to the front of the chair cover matching the top and sides.
Next, you'll need 2 packages of double-fold bias tape. You can get these from any fabric store. Put the front and back pieces of the highchair cover together, flannel sides together, vinyl sides out. Pin the bias tape all the way around. Sew it on.
Next, measure the length of the ties, add that up and cut a piece of bias tape that long. Sew the bias tape closed. Cut the long strip of bias tape into 6 equal strips. Using the original as your guide, mark where the ties go and sew them on using a zig-zag stitch. Sew back and forth several times.
That's it! It's easy!
