Circular needles – KnitPro needle sets are my circular needles of choice, 1 set and you have most of the needle sizes you want with 4 different cable lengths, stitch holders and a ruler/needle sizer. ( I have both the nickel and wood and a few extras!)
Short straight needles- Art Viva 20cm Tasmanian Oak are lovely to work with and are my preferred scarf needles. For larger things I prefer the circulars
Crochet hooks – required for picking up dropped stitches. A tiny one, a 3.25mm and a 4mm on hand all the time.
Tape measure. – Can’t make any garments without one.
Nail scissors – for cutting threads. I find these better than craft scissors as they are finer. The curved point minimises my risk of cutting the wrong bit.
Knitters needles – Chibi come in a screw top tube so less likely to lose one, now I have the tube I just buy cheap ones when I need to. Knitters needles are better than tapestry needles as they have a rounded end to minimise splitting the yarn when sewing.
Cable needle – I like the bent ones they seem to sit better and don’t have to be held 100% of the time.
Stitch markers – I don’t use them a lot and I certainly don’t mark every repeat across a row. I do however like to use them to mark things like the start of a round, dart points, raglan points, side seams, centre stitch where the spot is not obvious from looking at what has already been done.
Stitch holders/ end caps. – I rarely use conventional stitch holders these days; just screw the end caps onto the cable and you have an appropriate sized stitch holder without transferring the stitches.
