www.shewasvain.blogspot.com is actually my favourite DIY site for Muslimah's all around. She has so many awesome tutorials, that she has a section just for DIY on her blog header. From how to cut your own pattern for a basic abaya, sew a Rabia Z inspired shayla, her tutorials are the best out there. They rock!
Fabric panels inserts are some of the biggest trends in Khaleeji abaya designs right now. Ange from http://www.misshijabi.com/2012/06/diy-turquoise-panel-abaya.html does a great basic tutorial on an old abaya. I like to add an inner tying belt on fabric panel DIY abayas to give them that chic factor. I should probably make my own tutorial for that.
Tutorials for DIY scarf hangers: 1. out of regular hanger, with glue gun, ribbon, and shower curtain rings http://www.smartnsnazzy.com/2012/01/diy-compact-scarf-hanger.html
and #2 just shower curtain circles and a hanger http://petitenchic.blogspot.com/2011/08/diy-scarf-hanger.html
Now I totally remember blogging this simple DIY turorial a long, long, (probably 2008) time ago. But then I realized, it's on the old BM blog account. Ooopsie.
Anyways, if you are into Khaleeji style you probably end up with more black hijabs then any other shade. Hijab pins (tailoring stick pins) can be bought at no expense even in the West, but nothing sucks more than obvious boring pin in a smart hijab style. Soo, DIY is simple, nailpolish the tip of the stick pin the shade of your desired scarf. Photo courtesy of http://annonymousgirldotcom.wordpress.com/2013/02/05/d-i-y-colour-your-own-hijab-pins/
