Well...the other day, i was thinking about this method and may have an idea to improve just a bit on the very popular Magic 8 method. Nothing earth shattering, but just something to consider...Plus i've created a cutting chart and sharing a slick way to trim all those half square triangles!
So let's begin at the beginning.
How to make 8 half square triangles using only 2 fabric squares.
To make a Magic 8, first determine what size finished half square triangles are desired.
To make 2" finished half square triangles,
Add to the 2" measurement, 7/8". Your total is now 2-7/8"
Multiply 2-7/8" by 2. That equals 5-3/4".
(2) 5-3/4" fabric squares are the size needed to create (8) 2"
finished half square triangles.
** improvement: cut the 2 fabric squares 1/4" larger. For the above example...Cut (2) 6" squares instead of 5-3/4". This will allow you to trim your half square triangles for more accuracy. For those very accurate quilters, this step may not be necessary.
Here's how to make a Magic 8
Take your desired fabric squares and place them right sides together.Draw 2 diagonal lines corner to corner
Stitch a 1/4" on either side of both drawn lines
Cut the stitched fabric squares apart, resulting in 8 half square triangles. There will be 4 cuts. With each cut, be careful not to shift the fabric squares.
The first is a vertical cut, right down the middle.The second cut will be horizontal...again, right in the middle.
The third cut is corner to corner
and the fourth cut is the opposite corner to corner
Voila!If the fabric squares shift a bit, the extra 1/4" will allow one to trim for accuracy.
Now for a great trimming trick...
Say you need to trim your half square triangles to 2". Draw a diagonal line using a dry erase pen on an acrylic ruler. In this example i've drawn my diagonal line 2" down from the corner of the ruler. If you want to trim half square triangles to 1-1/2", the 'dry erase' diagonal line would be
1-1/2" down from the corner of the ruler.
Line up the 'dry erase' diagonal line with the seam, and trim. EZPZ! This trimming trick is shared from Corey Yoder of Little Miss Shabby
Here's a chart to help determine what size fabric squares to cut for the desired Half Square Triangles. The unfinished size is also the trimming size which includes seam allowance.
