Sand and Stone Thread Set










Cotton Thread- For Quilting and Sewing! - Sand & Stone Set - 8 Spools, 180 Yards Each
-
The Madam Sew, Sand & Stone, Cotton Thread Set consists of eight neutral tones that are great for quilting and sewing. These colors work well with a variety of fabric colors and prints making this a basic and versatile thread choice to add to your collection.
The thread is made of 100% long-staple, mercerized cotton. This is important as you’ll get less lint which means less fuzz building up at your needle and less thread breakage. Because it is cotton thread, it won’t be overly shiny and you’ll also be able to use it for any application where the end project will go in a microwave (think Bowl Cozy or Potato Sack).
If you are looking for a quilt thread that will add depth, texture, dimension and pop to your quilt top then this thread set is a must to try. The 50s/3 thread is made of three 50wt plies and has a final weight of 30. It’s thicker than thin 50wt threads so it won’t melt into the background. Instead, your quilting will have an opportunity to shine and your project will be strong enough to hold up to repeated washing or wear.
If you sew and want the feel of cotton or a cotton sewing thread that helps your decorative stitches stand out, try this set in your next project. It’s also nice for topstitching too!

Specifications
Each set consists of eight small cross-wound thread spools of 180 yards each for a total of 1,440 yards of thread in the set.
Colors:
The below picture shows the colors of the thread spools in this set. Please be aware that there may be a little variance from the actual colors based on your monitor or phone. (For reference: 002 is White and 001 is Black.)
Weight:
Our thread is a 50s/3 thread, which means there are three 50wt plies twisted together to make the thread. The final result when using the “weight system” of measurement is a weight of 30. That is because 30 kilometers of our thread weighs 1 kilogram.
Instructions & More
Use a 90/14 - 100/16 universal needle. We tested this thread with the 90/14 universal sewing machine needle and it worked fine. It’s always best to test on a two piece swatch to see how it sews. If it doesn’t run through smoothly, switch up to a higher needle size.
If you are looking for a comparison between our thread and some other familiar threads, we’ve done a little quilting and sewing comparison for you in the pictures below. We used Gutterman’s, Ours and Aurifil for these.
