Heavy To Show, Thin To Blend

Some have asked "What weight thread should I use for the top of my quilt project? Should I use a 20 30, 40 or 50 weight?" The answer is that it depends on whether you want the thread to blend or stand out?
A good rule to remember is "Medium/Heavy To Show, Thin To Blend".
If you use a decorative thread, most likely you want to add dimension to the project and highlight the thread. Therefore a medium to heavy weight thread is recommended.

Brytes by Caryl Bryer Fallert is a 30 weight thread.
How do you know which thread is heavy and which thread is thin?
Remember that the smaller the number, the thicker the thread.
Below is a chart outlining some our thread selections with the respective weight.
WEIGHT EXAMPLES:
17 wt. Perfect Quilter
19 wt. Poly Quilter
30 wt. Brytes
35 wt. Lava, NiteLite, Extra Glow

50 wt. MasterPiece, So Fine
60 wt. The Bottom Line

#810 Zebra Rainbows/ 40 wt.
A lightweight variegated thread will not be as visible as a medium, heavier variegated thread. Therefore, most lightweight threads are not variegated.
Although our grand daughter Avilyn couldn't imagine why anyone would want to quilt with any thread that wasn't pink.

She is now considering blue because it matches her eyes.
