I bought the softest pair of pants a while ago… I got them particularly because they have pockets which makes working in the garden much easier…
unfortunately, they are a little big and I was worried that putting my phone in the pocket might pull them down…
I dug out a needle and thread and sewed along the seam on both sides…

came out great, just tight enough so there are no worries about falling down, lol…
way to go me;-)…
