This blanket has been inspired by the character ‘Demelza’, from BBC’s Poldark (2015). The designer, Catherine Bligh, used Demelza’s colour palette and incorporated her love of flowers into each square. You can find this free pattern on Ravelry
Gauge is not essential for this project. As a guide, the big central square turned out roughly 16 inches , worked in Stylecraft Special DK with a 4.5mm hook (making the blanket as a whole ~55.5 inches across). If your central square is smaller, your blanket will be correspondingly smaller. If your square is bigger, your blanket will be bigger. Use what feels comfortable to you with the yarn you choose. Some tend to have a tight gauge; use your own judgement as to whether you want to go up or down a hook size, or even two!
There are two pattern documents: one with plenty of images to help with particular steps or stitches, and one without images, which is smaller and more printer-friendly.
