Anyone have experience sewing your own bras?

I'm interested in making my own bras or at least learning how to properly alter my bras. What are some good tutorials on the web?

If you want to make your own bra I highly recommend looking at the Clothhabit sew-a-long... http://clothhabit.com/category/bra-sew-along/ She posted some great resources regarding patterns, supplies, and tips on pattern manipulation.
In terms of sewing your own bra I recommend starting with a good pattern like the Classic Pin-Up from BraMakersSupply.
This is a Finnish site where you can buy all supplies for making a bra, fabrics, patterns, etc. Supplies/fabrics don´t come in many colours though, there are only black/white (was there also nude..?) but you can always cover the cups with any other fabric you like!
There is also a video tutorial for bra-making :)
