There is an accordion wall mount drying rack that can easily be pulled out from the user’s wall of choice to hand wet clothes. The drying rack is manufactured by Everbilt and sold by Home Depot for $19.98. It holds up to 35 pounds. A possible limitation would be hanging the wall mount by oneself.

The Miracle Fold Laundry Folder can be purchased on Amazon for $22.99. One can place shirts onto the board and fold the segments of the board, resulting in a perfectly folded t-shirt. This product is used widely in retail stores but could also be of use to people limited to one-hand mobility.
Carex Zipper and Button Puller is another device that could help people with hand immobility. The button puller can be used with one hand, attached to the button or zipper of choice, and pulled up of through the button hole. The product can be found on multiple websites, but I found the product on Health Products for You; it is priced regularly at $16.99.

On RehabMart, there is a sock sorter ring that can clasp sock pairs together. However, this design is not necessarily beneficial for people with one hand; it may be hard to maneuver the ring around both pairs of socks. Nevertheless, the sock sorting ring can be purchased at list price for $30.65.

The non-stick mats exist for several purposes, but one extreme use is to put garments on them while folding to prevent clothes from slipping off of slick surfaces when folding them. Using a non-stick mat could help someone with one hand to more efficiently fold clothes. The mats are manufactured by Skil Care Corp and cost upwards of $40 per mat.
