Quoting Momma +2 Girls:" How bout um... are they the ones that just have the one piece under your belly or do they also have the ... [snip!] ... that goes over your belly? Also, i wonder how easy it would be to make one instead of buying... couldnt take much material..."
the one i got from motherhood maternity online was just a belt under the belly. I can't stand a lot and def couldn't while I was pregnant on my stomach. I also was really huge plus size and belly wise so it was about the only thing made for bigger girls (it comes in smaller sizes.) I imagine if you know how to sew you could make it easy since it was literally just about a 6 in wide elastic band with a velcro patch in front it adjusted in back to be smaller tighter etc but if u make it urself u can probably do that too...hindsight I could of made it probably cheaper.
