Rather than natter on to you about the different ways to use the transparent qualities of silk organza, let me show you Jeannette Meyer’s class samples. I checked and she is fine with such sharing.
Two curved sets of strips are woven together and sewn around the edges to cotton organdy. The trick to such weaving is to leave a half inch uncut at one edge of your fabric piece. In the sample above, those are the left and top sides.
A wonky log cabin block with edges sewn with a machine buttonhole stitch. Fun secondary shapes are made with the irregular seam allowances.
A log cabin block with hand sewn pojagi seams.
Flat fell seamed transparent fabric over silk screened fabric.
Machine buttonhole stitched fabric pieces over tucked cotton organdy. You can use matching or contrasting thread to sew the tucks.
Origami folded cotton organdy blocks. Just don’t ask me how to make these. I missed that demo due to issues with my rented Bernina.
These are just a few samples of what we learned in class. It’s fun to play with the different effects you can get by changing which color of organza is on top. If you want to try this kind of seaming at home and are a perfectionist, try 100 weight kimono silk thread for hand sewing. I’m told that Superior Thread’s Tiara line of silk thread is good as well, though it’s a 50 weight.
What kind of art quilts can you make with these techniques? Here are three examples of Jeannette Meyer’s work she brought to class.
I think this piece is part of Meyer’s Storylines series.
This piece uses tapa cloth with the wrong side up. Jeannette searches out “spoiled” pieces to use. All those dark lines are sewn in. I gather Jeannette’s sewing machine doesn’t like this material.
Crucible is even more spectacular in person.

Beautiful and interesting work! Thanks for posting!
Those are really interesting effects. So far outside my comfort zone! I especially love the Storyline quilt.

It’s a bummer that you missed the part about the origami folding–it look very nice! All of the techniques are interesting–a whole new direction in creativity!
I was told the origami technique was from Mary Mashuta, but I haven’t yet found any links to it. And it’s been fun to use different types of fabric differently. There are pros and cons of see through fabric. Hiding knots is interesting.
I have used silk organza in my Off the Wall II. It looks great with paper lamination and foil. http://maryvaneecke.com/2013/11/12/off-the-wall-ii/
Mary, I’m so sorry my spam filter held you hostage for a bit. Love to see examples of silk organza in art works.
