Ok so tips about all thats good about DIY...
When stenciling the first step to wonderful stencils is a wickedly sharp x-acto knife or the kind of x-acto that has one blade with breakable sections...then make sure that what you want to stencil is in a stencil-able form...if there are islands of color that aren't connected to other islands that color your in trouble...and the easiest paper to use when startign out is printer paper that is covered in clear packaging tape on both sides...this makes sure that it won't warp terribly after you spray/paint on your stencil for the first time... and good luck!!!
Pinning Clothes (for modification)
If your trying to modify a shirt or other article of clothing and you know that you'll be pinning it with the personin the person in the clothes...make sure it's inside out so after your done pinning you can just begin to sew...and be careful...Jo told me it's painful to get a pin in the armpit...lol
So if you have a hemming job that needs to be done quick here are some options...
use ducttape or packaging tape and tape the end up so it's the right length...then iron so theres a nice end...
Staple or safety pin it and be you...that is lazy you...lol
after that temporary hemming use a machine and sew along the bottom or hand hem it so theres no seam line...
