Side gusset

My youngest has a favorite shirt that was getting snug. To prolong the life of the shirt and make her happy, I added a gusset to the sides and up through the arm. First I picked out the side seams about to the elbow.

I had her try on the shirt at this stage to see how wide the gusset needed to be cut. Then I cut long rectangles of a similar weight black knit fabric and tapered the end by the elbow.

I put the right sides together, and starting at the arm, sewed in the gusset with a stretch stitch on the machine. To finish the bottom edge, I folded up a hem to match the sides and stitched across with black thread.

I was quite pleased with how the modification came out. The shirt fits better and looks like it was originally designed that way. My youngest is happy because the shirt is now much more comfy.
