Using Acuspark + the M7 to make a buttonholeby Sarah Ann Smith
Sarah set out to make her son, Joshua, a perfectly fitted button down shirt for Christmas. Armed with her new Continental M7, not only was the shirt precisely sewn but the buttonholes were simply easy thanks to the Acuspark app that walked her through every step of the process.
Sarah’s step-by-step of how to use Acuspark to make a perfect and precise buttonhole:
There are a couple screens of buttonhole options, but I used the basic one. Note the QR code in the bottom left corner (more info below).
As you can see from the screen shots, the tutorial walks you through the process step by step. Easy peasy…my kind of sewing!

This is what that buttonhole foot looks like in real life. You slide the button into the back, attach the foot to the machine, and it makes the perfect sized hole every time. I kid you not, I make SEVEN buttonholes, perfectly, in seven minutes, and most of that was repositioning to the next spot!
This Nancy Zieman (oh how I miss her!) tool from Clover is an improvement over the old-school metal one. Although I have a fondness for the metal one, this version allows you to center the ruler exactly on the button band and mark your buttonholes. The darker green slider notches into the grooves so it doesn’t slide up and down the center as you work. I wondered when I bought it why I thought I needed a newer (plastic, yuck) version. Now I know. Once again, smarter sewing.
Ended in perfect precision!
So, with 50 years of sewing experience (albeit minimal garment making in the past three decades), an excellent pattern that taught this greying sew-ist a couple new things, and the incredible precision of the Janome M7 Continental machine, I am a seriously happy camper. Even better, Joshua loves his shirt!
