Pojagi Patchwork Seam Allowances vs. Regular Quilting Seam Allowances
Seam allowances are tricky things. In traditional quilting, getting the correct seam allowance will make your life a lot easier. A scant 1/4″ means that everything will line up nicely when you’re finished and points will match.
Reversible pojagi patchwork seams are very different. They are stitched differently and look very different.
These seam allowances are all approximate. It is almost impossible to get a perfect 1/4″. My general advice is to not even try. Close enough is fine, just try to be consistent throughout your whole piece.
When making pojagi projects such as stained glass window hangings, you cannot treat these seams the same as quilting seams. They are totally different.
Why the seams are different:
1. Traditional Quilt Seam
Start with 2 1/2″ squares.

The 2 1/2″ squares join together to form pieces that are 4 1/2″ long.

Those join to form a piece that is 8 1/2″ long. Each square that was cut at 2 1/2″ finishes at 2″ square.
If you’ve been quilting for any length of time, this should not be new to you. But the pojagi seam is different.
2. Reversible Pojagi Seam
Begin with 2 1/2″ squares.

When they are joined with a pojagi seam, you can see that the pieces are different lengths on either side of the strip.

Pieces will either be wider on one side than the other (dark pink), or at least off-set from each other (light pink). Even if you are very careful to always join your seams in the same direction, it is very difficult to get seam allowances the exact same size.
The entire piece is much less than 8″ long.

They are just two different creatures. I will admit, in quilting, I do want my points to line up and everything to be exact, but attempting to transfer that tendency to pojagi would cause me to lose my mind, or at least my enjoyment of the process. That is one of the main reasons why pojagi designs look quite different from quilting.

If you want to try it, go ahead, but don’t say I didn’t warn you!
Now that you are warned of the dangers of transferring your point-matching tendencies from quilting to pojagi, feel free to try out some pojagi projects. Without the stress of matching, you might even enjoy it more.
