I changed the collar and the sleeve cuffs to have the same stripe pattern as the body except the collar is only two stripes.
I also thought the folded collar that the pattern called for was too bulky, so I just left it as one layer.
I’m not too thrilled with how the letter turned out, mainly because I didn’t understand what the pattern was trying to tell me. If anyone understands how to remove the stiff paper after you’ve sewed around it, please let me know!! I will most likely be re-doing that part in the next couple days.
