Ever since Steph of 3 Hours Past the Edge of the World first mentioned her plan for a flutter-sleeve hack of her Blank Canvas Tee pattern, I was on board. Totally. For realz. I waited patiently for her to come out with the hack, and read through her tute carefully.
And, of course, predictably, went my own way. I took a protractor, made a line 45° up from the edge of the shoulder (or, if it’s easier, at 135° from the line of the shoulder), and then measured a length from the edge of the neck that roughly corresponded with how long I thought the sleeve should be. Using the edge of the shoulder point as the centre of my circle, I made a partial arc of the circle down towards the rest of the sleeve (a compass would’ve been perfect for this but, being too lazy to head upstairs for the rest of the geometry kit, I just measured with my tape measure in several places.) Then I sort of free-handed, sort of used my French Curve, to approximate the rest of the sleeve. Oh, and I rounded the spot where I had drawn in my first angle. Steph’s method is probably a lot more precise.
Unfortunately, then I got cold feet. The sleeve looked too short, I thought. I lengthened it, re-drawing the curve, and cut out a trial version in my scrap jersey—the old knit bedsheet I bought at Hallowe’en for making Tyo a shirt. It doesn’t have the best drape, but it was available and cheap and not earmarked for any other projects at the moment.

Flutter sleeve: too long (original size), too short (cut line), just right (click to zoom in to see the "just right" line)
Predictably, the sleeve was too long. I stuck a pin in where I thought it “ought” to go, shortened, and cut again.
Now, I think they’re a bit short, at least at the very top of the shoulder. I actually think my original curve would’ve been pretty much perfect. So there you go. At least the angle seems pretty good.
Frikking finnicky flutter sleeves. At least they’re easy-ish to tweak going from longer to shorter.
I paired my trial, not-really-opaque-enough-for-public version of the tee with my red clovers, cuffed to a high-ankle length, for the purposes of the photos. I think I’m liking this length better, and they are *much* more comfortable with belt-loops, although the belt doesn’t help with the front-sag, since the belt wants to sit exactly where the waistband wants to sit. Anyway, we’ll see. The weather is a long way from ready for this look, anyway.
An interesting observation
Steph recently came out with the updated and finalized version of her BCT pattern, considerably refined from the early draft I used around Christmastime to make my versions. Curious, I eagerly printed off a new version. And then compared it to my version of the pattern.
The results were very interesting indeed.
For one thing, the pattern I had printed out (original size 35), whether through some quirk of the early drafting or scanning or my own ineptitude (always a possibility), was considerably smaller than the new size 35. Actually, it’s somewhat smaller than the new size 30 (for a 30″ bust). Which goes a long way towards explaining why my versions of the tee are so, well, fitted.
The shoulders on the old pattern were quite a bit wider (even in my shrunken print-out), as was the neck opening on the back, and the angle from shoulder to sleeve was more extreme. I suspect Steph was bang on in altering those for her new version :).
The original draft was quite short (Steph wears her trousers a lot higher than I do 😉 ) and I had added a lot of length to the bottom. The length of the new, longer draft is pretty much *exactly* the same as my lengthened version of the original. Win!
So, for the moment, I’m gong to keep on working with my old version (as I like how it fits), with maybe a few tweaks around the shoulder. But since I have thrown my versions out there of examples of what you may get from a Blank Canvas Tee, I thought I should also point out that I apparently printed mine considerably smaller than intended. If you want a tee that fits like mine—go down a size. 🙂
