Today I started framing the windows and doors that we cut out yesterday. I’ve begun by taking some 1/16th thick basswood that is 1/2 inch wide as my windows are, and using it make the casing. I had been considering using popsicle sticks, but the longest popsicle stick I could find at the craft store wouldn’t fit the lengths of most of my windows. Anyway you can see a progress pic up above. Since this is very small wood I used a crafter’s saw that is basically like a big X-Acto blade with a serrated edge to cut the pieces to size. I made sure that all pieces were cut to size and had a snug fit before I glued them into place. I think it is worth the extra effort to do this to your windows since it makes a nice clean straight edge, hides any errors you made, and also looks more authentic.
