My dad upholstered several Dux furniture pieces for me, but I have cats. And the cats frequently shed or puke on everything we own.
Hence, the need for slipcovers. Originally, I had a cotton fabric pinned around the cushions, but the sun exposure damaged it. Polar fleece I draped on the chair next to this one has no ill effects from sun, so I picked up some sale-fleece and got to work.
The bottom cushion has a boxing on the sides, but it was a pain to do. Even with pinning and a walking foot, the fleece stretched out, causing me to rework it several times. The top cushion I did a simpler construction, and it came out nicer, I think.
On to the next chair: a high backed version with a head rest pillow and ottoman.
