The wind is in from the Canadian tundra and the air has gotten drier and much colder — almost like winter. And that dreadful Senator Boxer from California has engineered a shortage of pseudoephedrine. Californians! What do they know of sinuses? I woke up the other morning and decided that the curves I’ve been thinking […]

Melisandean Flute Mélisande* gets half credit on this one, for suggesting that the paper on the edges could be folded down to hold the piece together. This model has a much nicer waist to it, more suggestive of an actual glass. I suppose the next step is to work on a stem and base.

I know that Eric has already blogged this, but this will not stop me from noting that lilzabubba (who is also known as Bekah) has made a rather more rational crease pattern for the lunoid model. And made a nice double lock on those troublesome corners — very clever, never occurred to me. lilzabubba’s Crease […]

This was one of my first models, I think – I was about 13. It’s corrugated for extra goodness. I had thought it one of my simpler models, but making a CP has taught me otherwise. It’s still fun. Here’s the crease pattern. And a Happy New Year’s to all!
