tip: directional prints on flip-and-stitch corners

there are lots of times when i want a directional print to be facing a certain direction when i'm making quilt blocks or components: hsts, flying geese, chevron blocks, economy block corners, snowball coreners, diamond block corners (like wensleydale), and more. in the star cornerstones for "pinky stinky edna" i want the pieces in the star points to be going the same direction as the center block. this is completely personal preference in this case, but it's an effect i'm aiming for.

these corner triangles are made with the flip-and-stitch method where a smaller square is placed right sides together on the corner of the base, a diagonal seam is sewn to create a corner triangle, the excess of both fabrics is cut off 1/4" away from the seam, the new corner is flipped out to replace the part cut off, right side up, and is then pressed into place.

so how do i get the print going the same direction from each side of the star?

this is the square of the strawberry print i want to add to the bottom left corner of this two-strip sashing piece. the piece is vertical and i want the strawberries to run in the direction shown in the photo.

first, i identify the direction the piece should be facing and then the part i want to show in the corner. for this one, the part i want showing is turned in the bottom left as shown above.

if i fold the top right of the square under the bottom left corner, i can see how the shape will appear once sewn together, flipped down, and pressed into place. the bottom left corner my finger is on is the part i'll use to orient myself when putting the right sides of fabrics together for sewing the seam. 

when i turn the square over so right sides of fabrics are together, i want that bottom left corner to now be in the upper right corner. that same corner that was under my finger in the upper photo is now where my finger is pointing in this photo. no matter the orientation of the corner, the thing to remember is:

 the corner of the square that you want to be the finished corner piece of the triangle needs to be place in the diagonally opposite corner when you have the square flipped for right sides together. 

so again, here that means the lower left corner (when the square is facing up and is in the direction you want the fabric to appear in) becomes the upper right corner when it's flipped over and the fabrics are right sides together.

when fabrics are right sides together, i mark the diagonal line i'm going to sew the seam on. don't forget to mark and sew the seam for the bonus left-over hst from the corner, too. 

once both seams are sewn and the corner cut off, the new corner piece if flipped out and pressed into place. and you can press open your bonus hst as well. 

voila!

i figure out these little tips for myself, often through trial-and-error, then i tend to forget them when i need them again. i'm going to start recording them and gather them together on a tips page for myself so i can remind myself what i've learned when i need it again. maybe it'll help someone else, too.
