I have a confession, I was never much of a starch user. That changed last night; starch is now my best friend, my sanity saver, and my favorite thing in my studio at the moment!
The project I have been working on this week has me tackling Y Seams for the first time. I have tried every way to do Y Seams that is out there and I am still struggling with them. (If you have a good trick for them, please share!) The end result was a finished block, but it looks like this:
Not exactly the block I envisioned! The pattern designer recommended using a copious amount of starch, so I started out with the light spray that I occasionally use, nope, still bubbly. Then saturated the block. It worked! Between the overabundance of starch and a hot steam iron I was left with a flat block! Queue the sigh of relief.
It is no where near square, but that is what trimming is for, right!?
So that is it, my ode (well not really, but you get the idea!) to starch for your Thursday morning.
(Best Press has no idea that I exist, but I highly recommend it. I ordered a refill bottle last night as soon as I discovered that it fixed my blocks.)

I used best press for the first time yesterday too and I LOVE it! I know what the hype is about now. My seams are flat and no flaky messes!
Fat Quarter Shop did some 8 point star tutorials on YT with Edyta Sitar and she shared some tips for Y seams: https://www.youtube.com/watch?v=qV-LPJpl0JU#t=810 it should be at approx 13:30 into the video (hopefully the link starts at the right time!).
I never used starch,,, before this year! All thanks to my SkillBuilder BOM. I’ve not used it for Y seams, but it’s great for keeping tiny and/or narrow pieces under control. Best Press was the only kind available at my LQS, so I have nothing to compare it to, but it seems good!
Glad you are tackling something new! I do not have experience with Y Seams, either, so no great advice from me, but I am glad the starch helped!!
