@Ohsewsimple  I imagine sheer means see through, like the edge of the snow. If it is on a dark background some will show between the stitching and  it will give the right effect of light falling on the curve

@Kenora  That's easy, just pick the colours!

If you sew for others, I would keep a rag bag of offcuts from shortening things.  Then you can test stitches on a similar fabric before you tackle the real stuff.

Unless it is a transparent fabric you can get away with any colour, but if I use it for a seam I change the  colour  of the left needle thread.at least in case a tiny bit shows on the right side.  I like to use toning colours if I can, but sometimes in an emergency I go with what I have in the loopers,

And just found this:

What type of quilt will we be making in 2020?
Every year, the style of the Murder Mystery Quilt is slightly different.  In 2020, it's an ombre quilt, in which separate blocks intersect to create larger designs in the quilt using a gradient of color that gives movement and magic to the finished design.  We will use a combination of traditional piecing, applique and a limited amount of foundation paper piecing to sew the blocks; each month, the block style varies, so it's never too much of one thing, and you get to try new techniques as the year goes on!  The finished quilt measures 72" x 60" with optional borders.  It's just lovely, and we can't wait to sew it with you!

Join our hero, Kitty, in Ancient Egypt!
Kitty Campbell is saddled with a social media intern at a museum in Amsterdam when she gets a call from an unlikely source, with an unexpected request: look into the mysterious death of an archaeologist on the road to Cairo.  The catch? The victim died inside a cargo van, locked from the outside, and carrying ancient artifacts from the tombs of Luxor.  Kitty is drawn into a mystery fueled by a web of lies--and it's her expertise in prehistoric plants, her skills as a lockpicker, and her unique understanding of the human heart that will help her catch the killer.
Egypt, a Land of Jewels and Mystery
Kitty, an exceptional archaeologist and sometime lock picker, can never resist a puzzle.  When a body is discovered on the other side of a padlock with no explanation, it's just that obsession that allows her to see what the authorities miss to solve a mystery that deepens faster than the night falls over the pyramids.  Through the story and the quilt, you'll follow along and investigate the mystery alongside her! Experience history, wild scenic beauty, and a range of memorable characters while sewing alongside a community of smart, witty, friendly and warm quilters like you!

Lovely, but not for me either thanks.  I shall go with what I have. Don't like it enough to spend more. (I meant I don't like the project enough to lay out more money)
