So let’s get to it.
With the success at my first try, I quickly decided to modify two pairs of pants I wore during my previous pregnancy. They have thick and short bands which I found not comfortable at all. I can’t believe how they have worked previously. So I removed the thick elastic bands and replaced with tall bands of soft knit fabric which covers the whole bump just like the pants I tried in store.
So in one afternoon of a weekend, I changed from having zero pairs of comfortable maternity pants to having 3 pairs.
Another good thing about the maternity pants with stretch band that covers the whole bump is it smoothes out the bump. With a loose fitting shirt on top, it prevents you from spilling the beans before your pregnancy is well established and you are ready to make the announcement. Of course, I spill the beans here by posting this Instructables before I'll make announcement off internet.
