Sure, the pockets that I initially thought would work often have to be deeper, or have smaller openings, once I'm in motion. And early cellphones were pretty tiny, compared to our smartphones. I've done a lot of #pocket addition and modification, and I'll be doing a lot more.

Because of the fraying, folded the seams of the pocket in on themselves. Required a lot of pressing. #pocket #sewing

Zipper in place... most of the painters tape came off. Not perfect, but who is peering at the zipper on my pants all that carefully 🤪#pocket #zippers

After ripping seams, taped it all in place with painter's blue tale. I suspect there are sewing specific glues and tapes for this, but I don't have them. #sewing #pocket

Zipper pinned in place #pocket #sewing

Had to press the heck out of this using that technique. This material frays a lot...#pocket #sewing

Started this time using the traditional sewing of inside pocket over the outside and pushing it through. A bit tough to keep this straight, as the pant leg had to be pushed out and around while sewing. This would be easier before the pants legs were sewn. #sewing #pocket
