A pair of scissors.
calico
A pattern is pinned onto fabric, then cut around.
It depends on how much fabric they use on that dress/ material. They are around $200
Paper is a much more rigid substance than fabric, so your scissors will dull faster from cutting paper. Then, when you need a crisp edge on your fabric cut, your scissors may not be sharp enough to cut the fabric cleanly. I know that my mother scolded me roundly if I ever even thought about using her sewing scissors to cut paper - she'd always say that's what the kitchen scissors are for!
You use straight pins to secure the pattern pieces to the fabric before cutting. Remember to remove the pins before sewing, however.
I sometimes fabricate to my mom when I do something stupid.
I would say it depends apon the fabric you use
To wash a wedding dress, use soap and water or OxyClean for tough stains, and iron it using a piece of ironing fabric between the iron and the gown.
First I suggest finding a dress. This can be any dress, as long as it has puffy sleeves (you know the type). I'm not going to lead you through the basics of how to make a dress. I'm assuming you want to dye it. Hopefully the dress you found is white. If not, bleach it. If so, then use fabric dye to dye the dress. I mean, once you find patters for all of the pieces (the corset/waist cincher, hair thing) it shouldn't be that hard. The corset thing I suggest making either out of felt or leather. The hair thing should be a thinner fabric. Cotton should do.
Cutting chiffon (and silk)can be very easy if you use a stabilizer. This is a thin soft fabric that you either pin, or Iron-on the back side of the fabric, and then remove when you are finished. There are many commercial varieties of this product which can found online and at most full service fabric shops. Ask for chiffon stabilizer.
You could hem it short. You could get some other fabric and add it to the outer layer of the dress. You could cut the sleeves off and make it a strapless. There is also fabric dye that you could use if you really like the style of the dress.
You should know the angle of the cutting tool. You can use emery sharp cutting tool.
