I made a Trench Topper. Here's the pattern from
Indygo Junction.

I made it in denim and I used some Anna Maria Horner "Drawing Room" as a contrast - the fabric is a Home Decor weight - can't wait to try it in some bags. Here are the corded buttonholes I did.

Ever used a thing to cut open your buttonholes? Here's mine - a little tap tap and voila!

Not sure how old these buttons are .... but I'll leave the discussion about my local haby / wool / ladies "fashion" / lingerie shop for another day .... needless to say, their buttons are vintage ....
I made a Medium size.

Miss Maggie just HAD to nuzzle in on the act ...
I added the contrast to the cuffs as well as the front facing ..
This is a great pattern. I was very pleased with how well everything went together. There are 3 main variations with lots of interchangeable possibilities. I added a facing for the bottom section of contrast - so that the weight was equivalent with the denim. It's lime green cotton drill ...
Ok, so now should a trench get in my way .... I'll be ready to TOP it!
