Based on a review of the remnants, I have enough to do 17 stripes (per sock). With this yarn, I generally use 9 stripes in the leg (not including cuff) and 10-11 stripes in the foot (not including the toe) - so I’m 3 stripes short (1 in the leg and 1-2 in the foot).

Solution: I’m going to do the cuff, heel and toe in the blue Heritage and I’ll have to insert one stripe into the leg and 1 or 2 stripes into the foot. I found a remainder of yarn (don’t know what it is but it seems superwash / sock) of which I have 6g. Each stripe takes a gram so I’ll aim to use it for the 3 stripes per sock. If I run out, I can use an extra stripe in the blue (used for the toe, heel, cuff), in the foot.

Update: Given that I need to leave tails on both sides of each colour change, each stripe of the green remnant sock yarn takes more like 1.5g. So I’ll only have enough of this to add one stripe into the foot. If necessary, find another sock yarn remnant (but I think one stripe in the foot will work, esp as I can do a deeper toe (in the Heritage, of which I have lots).
