Surely you can get this boxer shorts design anywhere, right? In my brief search (groan now for that pun), that seems not to be the case. Why not? Is it aesthetically challenged? Nope, this bikini example proves otherwise.
It turns out that the soccer ball's pentagon/hexagon arrangement is impossible to precisely map onto flat fabric. And while the aforementioned bikini example hardly has, um, flat surfaces, it still could only use an approximation of the pattern.
After a bit of trial and error, I came up with my own approximation that works on surfaces larger than a bikini. I think it looks decent, but I'll let you decide. Remember that the main take away from this instructable is that you have a template for building a soccer ball pattern on clothing. You can certainly use any means of getting the pattern physically onto the clothing (e.g., magic marker, spray paint, iron-on transfers, etc.), but I've simply documented a sewing example.
Step 1: Get Materials and Equipment
• A pair of plain white boxer shorts
• About 2 square feet of black fabric, maybe a little more (no specific kind is necessary)
• A pair of sharp scissors to cut paper, cardboard, and fabric
• Thin cardboard to use as a cutting guide (shipping company mailers work great)
• A non-permanent marking pencil to mark up the shorts and cardboard (or just use a regular pen for the cardboard)
• A printout of the attached pattern to use as a layout template
• A sewing machine or a fabric-friendly glue (sorry, I have no recommendations on which brand of glue to use) to attach the patterns
• An iron to remove wrinkles from the shorts and fabric
• Optional -- masking tape to help with sewing and/or holding the patterns temporarily in place
Step 2: Prepare Materials
Use the pattern to mark up a single pentagon (the 5-sided shape) on the cardboard. This also doesn't need to be exact, but try your best. Cut out the shape from the cardboard.
Iron the fabric and shorts so they are wrinkle free.
Step 3: Cut the Fabric
Step 4: Attach the First Pentagon
Next, fold the shorts material inward along the edge of the attached pentagon and sew a seam from the inside of the shorts (or glue the seam from the outside of the shorts). Create similar seams for each edge of the pentagon. The original loose edges of the pentagon fabric should be completely folded into and hidden in the seam.
Step 5: Follow the Template
Attach two more pentagons as you did the first one onto the markings. Don't forget to create the seams that correspond to the black lines between pentagons in the template. Do this by folding the shorts material inward and sewing/gluing, just as you did with the pentagon edges.
Step 6: Continue Attaching Pentagons
Keep adding pentagons and creating seams until the shorts are covered. You might have to cut more pentagons from the fabric depending on how large your shorts are.
Step 7: Final Preparation
By the way, I tried sketching this thing out on Autodesk SketchBook Pro 6, but my drawing was so horrendous that I was afraid I would get expelled from Instructables.com. But I'm sure my sketch would've looked awesome had I been using a Wacom tablet with a full copy of SketchBook Pro...
