Pillowcase dress and bias tape

I finally got around to making a pillowcase dress for my daughter. End of summer, but she requested it especially long and I made the armholes deeper than planned, so she should actually be able to wear this every summer for most of her life.
I will direct you to a popular tutorial that I plan to use next time I make one of these, but, really, there are so many tutorials online for these dresses-some with ribbon casing at the top like this one, some with it through the arms, some with elastic, some from non-pillowcase fabric, etc.-that it would be worth it for you to look around and find the one that you like best. I looked at several and then, when it came down to it, followed none of them exactly. Probably why my armholes ended up so large.
I did make my own bias tape for the arms. I've done this before, but this was the first time to use my Clover Bias Tape Maker. Much less tedious this way. The package comes with instructions, but like everything else, online tutorials are abundant. To start with, here's one for making the tape and one for sewing it to your garment.
If any of you purchased floral sheet sets in the late 70s or 80s, or slept on your parents', you may recognize this pillowcase. This was the last in our household that hadn't been recycled into rags or dropcloth. I added the ribbon trim around the bottom to match the ribbon at the neck.
This is a simple sewing project, but if you're like me, problems seem inevitable until you've worked through it several times. I expect it will be faster and easier next time.
