Frigid Piecing - Part 3- Cut and Sew the fabrics!

Sub Cutting

If you have a few freezer paper triangles traced, you can pick a random CENTER of the triangle. Choose a point at least an INCH in from each side, and put a DOT (on the dull side is fine). Then draw a line to each tip of the triangle from that dot. IT NEED NOT BE IN THE CENTER. Now be sure that each sub triangle is labeled... A Light,   A Medium,    A Dark, B Light, B Medium B D, C L, C M, C D etc.

Only cut one triangle apart at a time, so you don't get confused..

Now you will IRON the shiny side of the Light freezer paper triangle on to THE BACK of the light fabric, the Medium triangle  is ironed on to the back of the Medium fabric.. the Dark Triangle on to the back of the dark fabric using the shiny side against the fabric... it SHOULD stick.

I usually align the OUTER edge of the triangle with the straight grain of the fabric, less stretching....

Now go to your cutting board and Using a Ruler with a 1/4  inch marking, you will use your rotary cutter and cut 1/4" away from the FP, giving you an accurate seam allowance....



Assembly of Block

Lay the fabric triangle, fabric side up, checking the L/M/D arrangement with your original drawing..(if the triangle was a real 'regular' i.e. equal sided one, you could easily put it together with the wrong edges together)

Analyze the triangle. the center has three angles. The one with the least Sharp, or the Most Flat triangle will be the 'set in' one. (Sew the shortest seam first, is also a good rule here) Therefore pick up the OTHER TWO and put them Right sides facing, and using Two Pins, poke through at the tips of the FP, and see that the seam should lay perfectly, and the Edges should be nice and neat, because you cut such nice 1/4" seam allowances..

Now, SEW right next to the FP, 1/4" from the edge, SEW ONLY FROM THE TIP OF THE FREEZER PAPER, TO THE OTHER TIP. Do not allow your seam to go beyond the cut tips of the FP. (I do backstitch one or two stitches but do Not sew into the seam allowance ) Press that seam OPEN, and leave the FP attached.


Set-ins

You will again lay the triangles out face up, with the third triangle in its place, I usually have the "assembled triangles" on the bottom, and the third triangle on the top. Flip the third Triangle down, so that the seam you will sew will be aligned with the triangle on your right. Pin the tips as you did before, and sew the seam from tip to tip.

Now, you can take the unit out and align the last seam. The FP will be RIGID, but you can fold it or crease it without worry, and use the two pins, sew the seam. These seams may be pressed FLAT, they do not need to be pressed open.

You now take the triangle back to the ORIGINAL drawing, and Pin it into place to the drawing.. Now work on the next triangle.

If you make a mistake, you can always just trace one more set of FP to try again, you have not ruined anything....

Oh, this is fun...!  isn't it?
