[IKEA] Speedlight Diffuser - Gary Fong's Lightsphere Style

Base solution by arturg: https://www.instructables.com/id/DIY-Gary-Fong-Lightsphere/ - it was a revelation for me, thanks :)

Just some pics of simple and really cheap diffuser for my 580EXII. The material is IKEA's desk liner - sold in 1,5m rolls for ~4$ (Poland).
I've put velcro on diffuser and flash - it's handy for other attachments too (color gels, anyone?) - for velcro config see photos.

Dimensions: 16cm x 50cm (width of the roll)

I've found one problem - it's too heavy for weddings, etc. - it often rotates speedlight end when switching position to/from portrait/landscape. So I'm looking for lighter material... bubble wrap maybe...

PS. Hooray for dirty mirrors ;)
