Here's the first one of my FIF shirts to become a tank

thanks! If you look closely, you can see how bad I am at stitching a straight line. I almost gave up on this one a bunch of times

I made this from a size L t-shirt that I loved but never wore. Five Iron Frenzy was my favorite band, and I missed a concert but gave somebody money to buy me a shirt. They came back with this (I never remember to take pictures before I start), but it was too big.

I traced an American Eagle tank I liked, and came up with this:

and here's the back:

start with a t-shirt (obviously)

do this kind of thing to it:

If the sides fit you fine, then you don't have to mess with re-sewing them, but what I did is cut the shape I wanted out of the front and a wide rectangle out of the back, the height of one side of the front:

I sewed them together on one side, put it on and figured out where to sew the other side. I then had a fitted tube-ish thing:

Cut two strips about 2" wide out of the rest of the shirt for the trim. Cut all the way through the shirt, the trim piece needs to be long.

Put the ends of the two pieces together (right sides facing) and sew to make one LOOOONG strip. Doesn't matter how long, just LONG.
I'm sure there's an easier way to do this (and I'd love to hear it), but fold the strip in half (right sides facing) the long way and sew to make a tube. Trim the excess material and turn it right side out. Fold this strip in half with the sewn part in the middle and iron it flat. Basically, you've just made your own bias tape. Sorry I don't have pictures for that step.
Now add the trim to just the very top part:

I cheated at this part and used fabric glue with my pins, since I neglected the ironing part. To add the trim, put the edge of the fabric inside the fold and pin. Then sew across it. I did mine twice because the first time, some of the trim came out from under the needle in the back and didn't get sewn down. I was tired because my neighbors woke me up with their stupid party, and I didn't know what else to do since I couldn't sleep. But in the end, I liked having the two lines there, it looks more professional.
Next you're going to find the seam of the long trim piece, where you sewed the two strips together. Start pinning that dead center of the back, and use up all your pins as you continue pinning the trim piece to the tank.

(Make sure you have enough bobbin thread) Start sewing at the end of one strap and go all the way to the end of the other strap.
Next, put on the shirt. You could even cut the straps and leave it as a halter top, or you could have someone safety pin the straps where they look good and carefully take the shirt off and sew the straps to the back.

I thought about using a snap or button to make it into a 3-in-one deal: tie the straps behind your neck, attach them straight to the back, or criss-cross. You might want to try that... who knows?

can't see either

my husband fixed his pants with binder clips.

Back story: I recently inherited a sewing machine from my great-grandma, and I had already set aside a sewing area, but now it's full of boxes and stuff. Rather than clean it off, I set my sewing machine (sans table) on the floor in front of the tv, and that's where I do my stuff. The foot pedal became the "knee pedal," etc.

So... The other night, I was sewing the strap of a tank top I'm reconstructing and pinned it like crazy because the material is a pain and likes to move on me. I set all this to the side as I worked on the other end of the tank. I just happened to move my leg, and set it on the strap as about six pins jabbed into my leg in a nice neat row. 

the ones I have are too thin.

I'm going to work on another one and I'll take pictures. It's too complicated for me to draw, and I made it a while ago. I'll try a simple one w/o pics.

Cut the bottom half off the hoodie, this will be the main compartment. Cut out a flap from the top half, and include a little bit of the top of the back too. It should be a rectangle, and it should include the hood.

Get whatever material will be your lining and make a basic pouch a little smaller than the main compartment. Now would be the time to add pockets to the inside, if you want to do that.

Trace the flap part onto the lining material and cut it out. Sew the bottom part of the hood shut (The part where you put your head through) and add a zipper if you want it. Put the lining and flap right sides together and sew them together, leaving the back part unsewn.Turn the flap right side out.

Cut the sleeves off and make them the way you want. Like I said, I sewed them so they were the same width all the way through instead of wider where they used to connect to the hoodie.

This is kind of tricky to describe, and not essential, so if you don't understand, you can do it however you want. Stretch one cuff over the other and hand-stitch the very end of the inside cuff to the seam where the outside cuff connects to the sleeve. Or you could do it the other way around. The way I did it, the outside cuff can be pulled back to show the inside cuff.

Arrange the flap and strap where you want them in the main compartment and then put the liner in.

I pinned it all so the unfinished edges were inside between the liner and hoodie and sewed around the edges, but I think you could work it so you don't see the stitches.

*shrug* hope this helps. I've been wanting to make another one, I just have to decide which hoodie to sacrifice. I'm a hoodie junky. My husband has one he doesn't like the way it fits, maybe I'll use that one.

Is it bunched like the front? Like, does the ribbon go through it?

yes; I love my Yasmin!

I don't carry a purse, and I like to keep all my cards and stuff together, so I wanted one that would fit in my pocket. I had one that came with a backpack but it wore out. My wallet fits my drivers' license, two check cards, two credit cards, my prescription card, Blockbuster card, and my Maurices punch card. Plus whatever cash I have at the time (usually none  )
