I had gauge issues with my projects ( set of 4 items) and had to make 3 gauge test squares moving down from 8mm and  yarn, to 7mm and  yarn, before I actually got the test square down to the size specified. The original called for 9mm and  yarn. Then when I actually crocheted the items, they are too small. And the stitch is unnecessarily complex, imho!
First item finished. I want to do other things, a shawl, a blanket, spinning, cookies, pottery. But I need to finish the other 3 pieces. One of which I have done but will have to comlpetely rip out and redo with a larger hook. And maybe a changed number of stitches too.
I think maybe I won't do this again! I do not need the aggravation just for a free pattern when there are so many others online and I can probably do any of these things without a pattern anyway.
