Redwork was very popular in the 1870’s as a form of embroidery. It is a technique of stitching using red cotton. Not all colors were colorfast in that time and that’s the reason red was the initial color of choice because the dye, turkey red, was colorfast and durable when used on cotton thread. Another color that was popular at this time was indigo blue – thus the advent of Bluework

The most popular designs were for children, or floral designs. This form of needlework was very popular among the masses because the only stitch required was a straight stitch. Simple stitches such as running stitch or stem stitch were easy to master by those who had not been tutored in needlework. The designs were stitched on white or unbleached muslin or even weave fabric such as linen and were used for everyday household linens or as decorative quilt blocks.

Penny Squares were very popular at that time. For a penny, needleworkers could purchase "penny squares" - the stamped squares of fabric that were readily available in catalogues or the local mercantile store. These squares could be put together to make a complete quilt.

Today Redwork is very popular. It is used in the same fashion as before but with the advent of Indie crafts it is having a resurgence of popularity and redwork can be found on all manner of needlework creations. I have been busy surfing for this article and have sourced free and not so free links for redwork patterns and designs. Below is a pretty comprehensive but by no means complete listing of interesting sites for you to peruse. Enjoy!
