It all depends on the look you want to achieve. I agree with Margo (and I will do that), to make samples.

And I agree with Connie as well - for my own taste, I will stick with the same kind of thread for all appliqués to keep the look uniform.

I have bought several spools of KingTut from Superior, I can't wait to try that!

I have used Sue and Pat's raw-edge technique on several pieces., mostly small things like wallhangings. If you are going to mix threads for the blanket stitch, be aware that the weight of the thread will determine how visible the stitching is. It probably would not be ideal to mix 50 weight with 40 weight, since the heavier thread may produce a more prominent edge, making some patches stand out more than others. It certainly would be fine to do all the appliqué with the heavier thread, if that is the look that pleases you. The other thing to be aware of is the sheen of the thread. Again, you may not want to mix a matte finish thread (such as cotton) with a shiny thread (rayon or some polyester) if you would prefer a fairly uniform appearance to your appliqué.

Having said all that, I will freely admit to grabbing whatever Coats and Clark's Dual Duty thread is handy and the right color for my previous projects! For the BOM, since I consider this an heirloom piece, I will probably stick with 50 wt cotton Aurifil or Mettler. But as Margo says, it's YOUR quilt, so do what pleases you!

I am new at this blanket stitch also so can't say for sure, but it might be worth our time to make samples using the threads we have on hand to see how they look, then throw the sample in the wash to see how the threads come through that. It will probably be time well spent as well as practice on the tricky corners!

Just wanted to add that some of my threads are Aurifil cotton 40 and 50 wt. this would give a mixture of poly and cotton in the quilt....

I am still working on my month 3 arcs, 4 done and 32 to go, had hubby in hospital for part of March so behind a bit....my question is, I have a mixture of threads both poly and cotton that are the right colors. Do you think that would be okay to use for the blanket stitching? I see Sue used all Mettler cotton, so am wondering if I should spring for new cotton threads? I have a bunch of Superior 40 wt Highlights and Mettler Polysheen, also 40 wt. I don't really have a clue as I mostly do needle turn appliqué, but want to learn the machine method. Just need some feedback on this.
