Finished the tomato warp this morning and wound the next one - a mixture of browns, golds and sage greens along with Carob brown Bambu 7.

I had purposely let my inventory of Bambu 7 dwindle, thinking I was done using it in production so when I went to put together the yarns to complement the textured rayon I was stymied!  There wasn't really enough of anything to do my regular production warp of 4 scarves.

So how much yarn did I have?  There was enough of the teal for a warp of two scarves (partly because I'd lost 6 ounces of the textured rayon in the rat's nest winding it onto a cone).  There was enough China Red for a warp for 3 scarves.  There was enough Carob for a warp of two scarves.  And there was enough Onyx for another warp of two scarves.  Good enough for test marketing a new line.  If I can get enough of them woven before the last 3 shows of this season.

How did I know how much yarn was left?  Our old friend mathematics came to the rescue.

Bambu 7 is equivalent to a 5/2 cotton so about 2100 yards per pound.  (840 x 5 divided by 2= 2100)  Divide 2100 by 16 (ounces in a pound) for a total of about 130 yards per ounce.

I weighed the cone (taking care to minus out the cone weight) then multiplied the number of ounces by 130 yards.  Voila!  I knew approximately how much yarn was on the cone.

It was a simple matter to then calculate the yardage needed to do a warp for 2, 3 or 4 scarves and see how long a warp I could wind with the partial cones I had left in my stash.

The article for Handwoven just got sent - and then I remembered I'd not included the drafts!  So I'll get that done and sent off.  And hopefully I can dress the loom with the brown/gold warp and weave a scarf yet today.

Another really pretty colorway! I use the same method for calculating the contents of partial cones. Usually I get within a few yards of the actual count, provided I start by weighing the same kind of cone in an empty state, so it's not apples and oranges when weighing the partial cone. Works amazingly well!
