- How To Use Half Square Triangle Paper to Make Half Square Triangles with Video
Supplies you will need
- 10″ stacker of Blue Carolina
- 10″ stacker of Confetti Cottons Riley White
- Triangles on a Roll 3.5″
- Tracing wheel for scoring the paper (alternatively, you can sew down the stitch lines with no thread in your machine before you pin in place to make it easier to rip off)
- Rotary Blade – this is where I found the pink floral one
- Cutting Mat – this aqua and green one is so cute!
- Clear Ruler – I really love this pink Lori Holt one)
****This will make enough blocks to make a 45″ x 60″ finished lap quilt using 3″ finished blocks, with a few extra left over.
How To Use Half Square Triangle Paper
- Trim down your 10″ stacker to 9″, so it will be the same size as the triangle paper
- Using your tracing wheel score the stitch lines on the triangle paper to make it easier to tear off (you can see this in the video).
- Making as sandwich lay down your white 9″ square with your printed fabric facing down so right sides are together. Then Lay the triangle paper square on top with the printed side up.
- Pin triangle paper in place so it does not move while sewing.
- Following the arrows, sew down each of the dotted stitch lines. You will sew four lines total.
- Trim edges and square up to make a nice even square.
- Cut down the diagonal lines so you now have four pieces
- Continue cutting across the vertical and horizontal lines to further divide the square into eight pieces.
- Gently press open and square up. The finished triangle (with seam allowance – once blocks are sewn together) on the roll says 3.5″, however, I like a little extra wiggle room and cut mine down to 3.5″ before they are sewn, so they will finish as 3″ blocks. This is just a personal preference.
