Struggling to fing the stitch, the gauge over a paper pattern is not that easy.
1st swatch.- hook 2.5 46 dc over 138 chains.
2nd swatch hook 2.75 46dc over 138 chains. no difference on total size after 50gr.
3rd. swatch hook 2.75 To improve the look of the stitch I inserted the hook on the chain instead of just all around. The change gave me an uneven stitch and the fabric was waved.
4th swatch (next project with this stitch) a chain for each dc.
Despite de gauge runs smaller than the pattern I will continue with it as crochet always grows larger once you use it. specilly dresses.
