These are my favorite stitch markers. They don’t snag at all. Mine are medium because that covers the range of needles I use most, but they have other sizes. If these are too pricey or you just want something a small metal ring works, too till you find what you like best.
These Clover lock ring markers are the ones I use for pinning to the fabric if need to for some stitch. Also handy for hanging on a dropped stitch to hold it till you can fix it on the next row or till you tink back. (You can also find coil-less safety pins that work well, but I find I get poked with those. They are usually in the beading section of craft/fabric stores.)
Small retractable tape measure something like this. Doesn’t have to be this one. -
I can’t find the scissors I have, but they are small and have a tip protector on them. I keep them in my knitting bag and the protector is nice so I don’t stab myself every time I reach into my tool bag!
Now to authors. I’ve read most if not all of these authors and liked them. Some are mysteries and some not so check them out on Amazon to see if they sound like something you’d like.
