That's the basic premise of the "Crossfire" chute from Top Flight, which is what you see in the picture. I don't think I can sew strait enough to make one that large myself.
Moved onto parachutes more than 20 years ago. I got a hotknife blade to fit my Weller soldering iron to cut the nylon and sewed up my first chute, the one I used in my all scratch Conformation rocket. It looked like a hot air balloon coming down 
I somehow managed to retain what I learned in the 8th grade. I've never made a parachute larger than about 36", think I'll take a stab at something a little larger.When grandma's eyes started going bad she taught me to use her sewing machine. I was 13-14 and very active so I'd wearout or rip my clothes a lot. I learned patching my own pants
