100 grams of spun purple (all I had) minus one sample skein equals nowhere near enough for this much sandwich.
I didn't weigh my portion before I spun it, but I'm estimating from such a full bobbin that it's more than 100 grams - closer to 150 I think.
Problem. That purple was a one off, individually dyed hank. What to do ... what to do ...
I'm rather fond of all things purple and blue & tend to collect them. I know - I'll go stash diving!
One trashed stash room & an hour or so later I emerged with another purple 100 gram roving. Score! It's not exactly the same (this one has a blob of blue near one end), but combined with the sandwich it should be close enough to fudge it. Now all I have to do is spin it up & hope for the best.
