When I made mine with denim, the ball ended up being 2.5% larger than the calculation predicted. If you're picky, you can compensate for that by dividing the result of the formula by 1.025.<br /><br />If you want to make the 6-panel design (a hosohedron/beach ball), the dimensions of the peels are as follows:<br /><br /><b>Peel Width = ball diameter × π ÷ 6<br />Peel Length = ball diameter × π ÷ 2<br />Curve Radius = (W^2 + L^2) ÷ 4W<br />Distance between compass points = 2r – W</b><br /><br />Draw a line equal to the result of the fourth formula and use its two endpoints to position a compass. Adjust the compass to the necessary curve radius and use it to draw the curves from those two points. Or use a computer application such as SketchUp (which is free) and use the endpoints as the centers of two circles. To ensure you drew the peel correctly, measure it and make sure its length is half your target circumference (which is diameter × pi) and its width is equal to the circumference divided by the number of panels you're using.<br /><br />If you want to make a beach ball with more than 6 panels, just substitute the number of panels for the "6" in the first formula. The other three formulas will still work as they are.<br /><br />---JoshuaJoshuacliftojmhttp://www.blogger.com/profile/17733411958526698005noreply@blogger.comtag:blogger.com,1999:blog-4995104313276785476.post-54233282695455853752014-04-12T09:35:07.593-07:002014-04-12T09:35:07.593-07:00Hi Vania!
Boy, that's a good question. If yo...Hi Vania! <br /><br />Boy, that's a good question. If you use the 12-piece pattern, it'll be more stitching, but the pieces will be smaller and all the sides will be straight, so setting up the pattern on the fabric will be simpler. <br /><br />If you use <i>this</i> one (6-piece), you'll have fewer pieces to have to deal with, but each one of them will be bigger, and they'll have a very specific curved sides that you'll need to get right. Regarding how many pieces to use for a large ball if trying this pattern, the answer is always going to be 6. You don't have to add more pieces for a bigger ball, just scale them up in size. (Same rule for the 12-piece.)<br /><br />Personally, I'd go for the 12-piece version. The more colors I can jam into a project the better, so the chance to use 12 different fabrics trumps 6. But that's just me. :3Kuhttp://www.blogger.com/profile/09264724402803175785noreply@blogger.comtag:blogger.com,1999:blog-4995104313276785476.post-12226762354574580312014-04-11T02:10:40.530-07:002014-04-11T02:10:40.530-07:00Hello,

It's also simple.<br /><br />Here is a PDF export of the current draft of my instructional document (http://www.joshuaclifton.com/How%20to%20Make%20Juggling%20Beanbags.pdf). It's 12.4MB due to being 159 heavily illustrated pages. I may not leave it on my server for long as I may someday publish it and I don't want it to travel too widely.<br /><br />By the way, good job on the photography and illustrations in your blog posts. I've only read the two related to making fabric balls, but you take attractive and effective photos of your projects and and I like the design of the text on the illustrations.Joshuacliftojmhttp://www.blogger.com/profile/17733411958526698005noreply@blogger.comtag:blogger.com,1999:blog-4995104313276785476.post-68274984130881539542014-02-24T22:47:38.529-07:002014-02-24T22:47:38.529-07:00Heck yeah, I'm interested in discussing this, ...Heck yeah, I'm interested in discussing this, but damned if I have the time... I'm really sorry, but this is my final semester of a grad program, and I'm up to my ears in other responsibilities. I'd really love to see your master thesis, though. :3 <br /><br />The circular curve just kinda fits my understanding of a three dimensional object... because the seams travel the circumference of the final shape, it made sense to me to make it a portion of a circle rather than a parabolic curve of some sort. If there's math to support that choice, I don't know it, either. ;_;Kuhttp://www.blogger.com/profile/09264724402803175785noreply@blogger.comtag:blogger.com,1999:blog-4995104313276785476.post-22038337878033237802014-02-24T15:59:11.478-07:002014-02-24T15:59:11.478-07:00Hey, I've been working on writing a document g...Hey, I've been working on writing a document giving mathematical definitions of a variety fabric ball designs (specifically for juggling) and I was very glad to find this blog post as it was the first (and so far only) confirmation I have found for my theory for the design of the beach ball (as I call the type of design you're discussing). Commenter Katherine's formula for the radius of the curve of the beach ball panel (or "peel") also helped a lot because I had to use trial-and-error before. Thanks, Katherine!<br /><br />I'm interested in learning where your theory for the shape of the peel comes from. I arrived at the theory empirically and I don't know enough math to prove it. I found an alternate theory recently that does not use a circular curve, but one based on calculating the circumference of a sphere at different latitudes. So far I have found very little information on making beach balls (technically hosohedrons) out of flat panels, and you are the only one who has said to use a circular curve. Some patterns I have seen use what appear to be other curves, or hand-drawn curves, and some even use different width:length ratios. Are you interested in discussing this?<br /><br />By the way, here is the title image for my document that shows SketchUp-generated images of all the designs I have defined (http://www.joshuaclifton.com/CGBalls.jpg), and here are photos of my proof-of-concept balls (http://www.joshuaclifton.com/Samples.jpg). I used the beach ball concept to apply curves to triangles and squares for the spherical tetrahedron, cube, and octahedron. I still don't like that I can't be sure if it is an optimal solution, though.<br /><br />Thanks for the informative blog post!Joshuacliftojmhttp://www.blogger.com/profile/17733411958526698005noreply@blogger.comtag:blogger.com,1999:blog-4995104313276785476.post-60248596315505209172014-01-18T00:58:36.589-07:002014-01-18T00:58:36.589-07:00Cool blog you got here and thank you for the valua...Cool blog you got here and thank you for the valuable information.
