Thank you, thank you for all the input on the pocket dilemma! Opinions were pretty divided (though definitely NO to just one pocket!), so I just went with my original decision, sort of. I had decided (before posting the query) that yes, I liked the pockets. Then, after everything else was done and the pockets were ready to sew on, I had a moment of panic and consulted Hubs. He likes the pockets, so on they went. I'm happy I did it. I think they just jazz up this casual shirt a bit.
Here it is! A comfy plaid cotton shirt, great for a day like today when the main activities are laundry, cleaning, and pillow fights.
The pattern is McCalls 6167. The changes I made were to remove the gathering and tie on the bottom pieces. To do this, I folded out wedges of the excess pattern tissue (meant to be gathered) at the waist, leaving the width at the hips and lower as drafted. This worked out very well and gives a roomy shape but more tailored look. I'm happy with it, anyway. :-)
How's the pocket scale? I didn't make them any smaller, but they do appear so, after finishing the edges.
I also removed about 3 inches from the hem. It still amply covers my butt, and I can still wear it with leggings, but it's less dress-like. Just a personal preference.
