Well my little guy has plenty of jeans and pant but not to many to just lounge around at home. I used to just put him in pj pants but he would freak thinking he's going to bed. So we bought 2 pairs of sweat pants but if he's messy those two are not enough.
All this to basically say I took one if those sweat pants and made a pattern from them. Then used those flannel receiving blankets to make him lounge pants. I cut out three and sewed two. I still have 4 blanket left but I am going to save those for when he out grows the ones I made
