Geodesic dome cover

I've spent the last week sewing a geodesic dome cover with my mom. It's been so fun and satisfying.  This is the progress I've made so far:

It's 13 triangular-ish "petals" that are 15' long and 5' wide at the base. Their sides are curved, each one is approximately 1/12 of a 60'-circumference semisphere. We added a 13th petal just so we have some wiggle room (better too big than too small). Even so, we may need to add a skirt, because it turns out the dome we're trying to cover isn't a perfect semisphere, but a little bit more, so it's actually 10'7" tall, even though it's a 18' diameter dome.

My mom and I bought the fabric in downtown LA at the Michael Levine Loft. We bought 70 yards for $51. We bought all woven fabrics, no stretch, very supple, some sheer. There were 8 pieces that were more than 5 yards long, 4 that were between 3 and 5, and half a dozen or so more that were less than 3. We sewed together some of the shorter pieces to make them longer than 5 yards, using this tape stuff to cover the rough seams and make them stronger. Then we cut out the 13 fifteen foot petals.

Right now we have sewn 4 panels with 3 petals each, leaving the 13th petal separate. The petals are sewn together using French seams because they're stronger (two seams) and prettier (no raw edges).

The next step is to add the thirty 4' straps for tying the cover onto the dome. These will be placed on the inner seams of the petals in 5 rows, the top two having 2 and 4, and the bottom 3 having 8 each.

We've also cut out some covers for the 30 vertices of the dome to make sure the cover doesn't snag on the bolts.

After we sew on the straps and sew together the panels, we'll leave one seam unsewn to act as a doorway, which we'll open and close with twine and some eyelets (...this is harder to describe than I imagined and I can't find a good image).

Basically, it's going to be (and sort of already is) friggin' rad. Hella wicked awesome.
