Force your fiance to teach you how to use his sewing machine. He made you those Katamari plushies, after all, which makes him like an expert.
During your down time, sketch pictures of what you want the end result to look like. Completely ignore the fact that you don't know how any of the individual items are put together.
Wait until your local fabric / crafting store has a giant sale. Spend way too much money on fabrics. Eventually listen to your fiance when he convinces you to also buy some crappy cheap fabric so you can make practice versions of everything you want to make.
Get home and decide that the first thing you're going to make is the floor length four panel skirt. Except you're going to make a short version with the shitty fabric first. Take some really inaccurate measurements. Waist, hips, length. Try to be off by at least four or five inches. It will add to the fun you'll have later.
Get out your large brown paper to draw the pattern on. The paper comes on a roll, so it will constantly fight you to roll back up. The only thing you have handy is a spray bottle, so lightly spritz it with water and put heavy things on it to weigh it down.
Realize that you can't draw anything on it while it's wet.
Come back a few hours later and draw your pattern. Forget to add seam allowances on the sides. Decide you don't want to draw it again, so just cut it out the way it is.
Fold the pattern in half and lay it on your fabric.
Pin it in place. Stab yourself multiple times with the pins. Use way too many pins. That will help you stab yourself more. Cut around your pattern and unfold.
Do this three more times.
Think about ironing the fabric to get out the creases. Decide it's too hot to turn on an iron. Instead, pin the long side seams together.
Sew everything together. Remember to remove the millions of pins you used. Get tired of being stabbed in the hands and arms. Try to make your lines straight, but fail.
Fail a lot. Once all the long seams are sewn think about ironing them to flatten the fabric. It's still hot, though, so don't actually do that. Fold the material for the waist over. Leave enough room to slip an elastic in later. Pin the crap out of it.
And sew! Leave an opening, somewhere, so you can get the elastic in. Ignore how the material seems to be bunching as you sew. I mean, try to straighten it out a little, but don't try too hard.
Cut a piece of elastic to the measurements you took earlier for your waist. That guarantees it'll be 4 inches to long. Attach a safety pin to one end and slip it through the opening of the waist band. Use the safety pin to guide it all the way through, till it comes out the other end. Pin the ends together and try it on. Discover that it is way too loose. Cut it so it actually fits and sew the ends together. Do a really shitty job of sewing it. It's not like anyone will ever see it.
Put on your skirt and stand on a chair. Have your fiance pin up the bottom hem. Give him only vague instructions and forget that he's only ever sewn plushies, and doesn't know anything about making clothing. Start sewing. Realize that the hem is crazy uneven, but don't stop. Just keep going. Also, fuck up sewing a straight line again.
And you're done! At this point you should have developed a Stockholm-syndrome like affection for your skirt, so declare that you love it. Force your fiance to say nice things about it. Make it a part of your wardrobe.
Now that you are an expert on sewing, start getting ready to make the rest of your outfit!
