We only have a handful of practices and scrimmage time is pretty short, so if I'm gonna have scrimmage vests they need to be practically free, not $5-6 dollars each!!!
I usually have 13-14 girls on a team and the most I've ever had at a practice is 13, so I figure 6 scrimmage vests should cover it. I bought 3 mesh laundry bags at Dollar Tree. Cut them in half and cut arm and neck holes. I sewed anywhere that that came unraveled from cutting and voila, 6 scrimmage vests. 3 even have fancy drawstring hems. This takes almost no time at all. Love it.
You do have to sew a seam on the second vest, sorry about the sewing:(
neck 9 inches (perhaps a smaller neck for younger kids than 5th/6th grade)
arms 8 inches
no hemming, just fast and easy, lets go play!
