Inspired by the cover of Nancy Warren’s “Mosaics and Magic” (Vampire Knitting Club series) (if you like cozy mysteries, you’ll love this series). I’m posting my pattern with the author’s permission.
https://www.amazon.com/Mosaics-Magic-Paranormal-Mystery-K...

This is my first time writing a pattern, so please forgive any mistakes or omissions.

Yarn: any Cotton DK weight (I used Universal Yarn Cotton Supreme DK in Yellow (520) for the background color (about 1 ½ skeins for a total of about 270 yds) and Teal (621) (about 1 skein of 180 yds))

I’m a loose knitter, so you may need to adjust your needle size and yardage according to your own knitting style.

New: this pattern has been translated into Danish by MarianneHo, and is available at this link: https://strikkeglad.dk/42783/lucys-mosaiktaske/

Needles: Circular knitting needle size 7 (4.5mm) in 24 inch length and in 36 inch length

Notions: 4 holders (for knitting straps in 3-needle bind-off), markers, scissors, tapestry needle for weaving in and mattress stitch.

Front panel and Back panel are knit separately with the same pattern, then sewn together with mattress stitch. The top edging is added to both panels, then the straps are attached using 3-needle bindoff.

The pattern includes links to videos for techniques used here.
