Here is how I made a receiver pouch and an insulin pump cover. Before starting, you should check the dimensions of your particular items. The receiver pouch mounts on a belt and could easily hold a camera or cell phone instead. The pump cover is similar to a shower cap in that it has elastic and slips over the front. You could use pre-quilted fabric. I free motion quilted 2 layers of flannel together (with batting in between).
First, the receiver pouch:
Cut a piece of fabric 12"x6", slightly rounding one end. Bind or finish the edges. Cut unquilted fabric 8"x2 1/2" for the belt loop. Sew the short sides together, 1/4" seam allowance.
Press flat with the seam in the middle.
Sew the belt loop to the pouch as shown, turning under raw edges.
Loop is 5 1/4" from the straight, bound edge.
Right sides together, fold up and sew, the straight edged end, 1/4" seam allowance.
Sew across the corners, as shown. Turn under and top stitch the sides down.
Top stitch the sides down and add Velcro.

Now for the Insulin Pump Cover.
I used the same quilted fabric as before. Cut a piece 5"x6 1/2". Then cut each corner off, creating four 1 1/4"x1 1/4" squares. In one corner, cut an additional notch out for the hose.
* Make sure you cut the notch in the correct area for your hose!
Sew the 3 similar corners together, right sides together 1/4". The notched corner will need finishing- I used a serger, you could bind or zigzag instead.
Sew on 7" of 1/4" elastic, extending into the notched area.
Sew on Velcro.
Here is the back finished view.
