My e-mails: email@example.com or firstname.lastname@example.org This wheelchair bag is approximately 10” w. x 10” h. The two straps support the bag on the arm of the wheelchair, although you do have the option of making three outer straps. There are several options in this tutorial. A key tab has been added to the end of the bag on the left for easy access to keys. The three pockets include an outer pocket, a front zipper pocket, and a pocket inside the bag. The Velcro straps work well for anyone unable to handle snaps, ties, or buttons. The latter could certainly be used depending on hand dexterity. This is a fairly easy-to- follow tutorial with many pictures, and full instructions for each step. I have also included a mini tutorial for a bag with a larger gusset, a gathered front pocket, and tab for holding a water/juice bottle in place in your bag. This tutorial does not include pattern pieces, only the size of each piece. All pieces are rectangular and easy to cut. PLEASE CHECK YOUR WHEELCHAIR TO ENSURE THERE IS AT LEAST AN 11" DISTANCE FROM THE ARM OF THE CHAIR TO THE TOP OF THE WHEEL TO ACCOMMODATE THE BAG. THE DENIM BAG AND BLUE TWILL BAGS ARE 1 1/2" OUT FROM THE CHAIR. I revised this wheelchair bag tutorial in 2017 adding a few more pictures, changing a few numbers, and adding options. I have had several ladies test it for accuracy and flow. I have not heard of any guidelines for using this bag in a facility, but you might want to check. Common sense plays a big part. The bag itself seems to fit closely to the side of the chair, so unless you have extremely narrow doorways and a wide wheelchair, this should not be a hindrance!
