Take a look at these block patterns:
Looks like you’d have to do a Right-Angle seam, doesn’t it? You don’t!
Here’s how you can make these blocks (and many more) with continuous, straight seams.
Continuous Seam Tutorial:
In the images below I highlight the seams you need to sew with a red rectangle. To clarify, you sew these blocks by placing the units on top of each other, right sides together, then open and press the seam as you like (whether that be by pressing the seams open or in one consistent direction).
Step One: Sew your center square unit to a rectangle unit, but not the whole way. Sew only the length of the red rectangle, but not inside the green circle. The key here is to sew more than 1/4inch long, and to leave more than 1/4inch of free space.
Step Two: Sew on the next rectangle unit, this time for the whole length (highlighted by the red rectangle). This is similar to sewing log cabin blocks, if you're familiar.
Step Three: Sew on the next rectangle, again for the entire length (highlighted by the red rectangle)
Step Four: To sew on the next rectangle unit, you'll have to scootch the first rectangle unit you attached out of the way. This will be easy to do because you did not sew within the green circle back in Step One. Attach the rectangle unit.
Step Five: You now need to finish the seam you started in Step One. Fold the first rectangle unit over the square, right sides together, and finish the seam you started, making sure to reinforce the start of this new seam by going backwards and forwards first. You're done!
Here are some pictures showing that last step…
Ready to continue this seam!
Can you see the white thread? That's the seam I started in Step One. I am pinning my units together and am going to sew, continuing that first seam to the edge of the unit.
I did it!
Do you like the block featured above? I will do another post soon with some more tips on assembling that block. Stay tuned!
