First I made a "light to dark" key by pasting up a tiny bit of each fabric.
Then I cut strips for sets that would be sewn together in light to dark order. I decided to join pairs first, sewing from the "top", down.
|Sewing strip sets|
After that I joined pairs into foursomes, sewing in the opposite direction ("bottom", up).
This keeps strip sets nice and straight.
|Pairs become foursomes|
Maximize useable fabric by keeping one end of the strip set lined up (as below).
|To maximize useable fabric, keep one end even.|
The other end will jog around because fabrics are never exactly the same width. That's okay.
|The "joggy" end!|
Instead of building sets the way I did, you could choose to join strips together in order, from left to right. Simply alternate the sewing direction (starting at top or bottom) each time a strip is added. Remember to keep one end all lined up, and let the other end "jog".
Why does "alternating" the sewing direction keep strip sets straight?
Feed dogs sometimes pull fabric unevenly. By alternating your sewing direction, you counteract the "pull" of the previous seam and prevent your strip set from curving into a giant smile!
However you accomplish it, your goal is to make strip sets that match the order of your project key.

Pressing techniques for straight strips:
Some people are happy sewing a bunch of strips together, and then somehow pressing all the seams at once. There is usually much pushing (of the iron), and pulling (of the fabric).
When I try it that way, strips stretch and waver, and sometimes the fabric doesn't open all the way and a fold is permanently rendered beside the seam.
So - I prefer to press as I go. It is not as quick, but my strip sets are straight, accurate, and crisp.
Here is my first pair of strips, sewn together.
|A pair ready for pressing|
Lay the pair on the ironing board in a nice, straight line and set the seam. To reduce the risk of stretching the fabric, I lift and place my iron as I move down the length. Never "push" it along the fabric.
In this case I wanted the seam allowance pressed toward fabric #2, so I placed that fabric UP so I could see it. The seam is positioned farthest from my belly.
|Setting the seam|
When the fabrics are opened (also away from my belly), the seam allowance automatically goes toward the top fabric (#2, in this case).
|Pressing in progress|
Straighten the strip along the ironing board as you work with it. The straighter you keep it while applying heat, the straighter it will be in the end.
Open the strip set and hold it in position with one hand. Place the iron on it with the other. Repeat along the length, resisting the urge to push & wiggle the iron!
|Crisply pressed, fully open at the seam, nice and straight - seam allowance pressed toward fabric #2.|
In case you are wondering, I am a steamer!
Technique is TWICE as important if you use steam because things can go wonky before you know it . . . BUT, if you practice good habits, steaming results in the crispest seams. Yumm!

Though it isn't quilted, this is now a FINISHED teaching sample! Whoop whoop!
