Ok...so here goes my first attempt at a tutorial...I have now realized why Paint is better that Photoshop for this purpose.
Ok...so to make the first t-shirt I began by just cutting horizontally underneath the armpits, to create a delightful tube.
Lay this tube over an existing t-shirt that does fit you the way you want it, and cut vertically up the sides about 2-3 inches in from the side of the t-shirt that does
fit you(depending on how wide you want the side panels to be. These will end up to be 4-6").
Save the fabric you cut out. If you want the side panels to be 5" each, trim the panels to be about 6" wide (for seam allowance). I chose to put fishnet overtop, so I laid my fishnet overtop of these panels and just cut out rectangles of the same shape (with a bit extra for seam allowance).
Next,...is a really simple step that seems complicated to describe. Reassemble your tube but inside out, pinning all 4 seams together. Flip it right-side out before sewing just to check that all the seams will look nice (I tend to make silly mistakes like this and have to unpick a lot of seams). Then...sew.
Whenever I say inside out, it generally means I have the two right-sides of the fabric (that will end up outside) facing towards each other.
Ok, not you have a tube that fits you and stops just underneath the bust. Re-attach it to your t-shirt (the fact that it's much smaller somehow didn't seem to factor in for me here; it could help to sew a sort-of L-shape while it's inside to make the sleeve/armpit/area-thing smaller. Sorry that's a really vague and confusing tip....
When I was doing this I just made it up as I went along. I cut diagonally from underneath the armpit of the shirt up to just below the collar. (I did the front & back seperately, be carefuly not to accidentally both layers at once).
I also accidentally just cut right through the collar and lost about 2 or 3" so I had to cut it up the center and add a button so I could get it over my head....although, I think it turned out the better for it .
Cut the sleeves to the length that you want them, keeping in mind you'll be adding trim.
I chose to also have an open back. After cutting out the shape, I just turned the edges under & sewed them so there weren't any raw edges.
Now...just flip the whole shirt inside out and re-attach the pieces you just cut off (now minus the trapezoid shapes). it should look pretty much finished except for the trim.
I cut the same fishnet material I used for the side panels into long strips, just over and inch wide and twice the diameter of the neck or sleeve holes they were intended for. Once again, sew them on inside out. For the neck I didn't put the two right sides of the fabric together because I thought the collar would bulge weirdly, I just sewed the right side of the fishnet (not that it really has one...to the inside (wrong side) of the collar.
I cut a slit up the collar, then I just sewed on a button on one side of my collar and cut a little whole on the other side for a button hole.
I think that's everything....let me know if anything needs to be clarifed or whatnot. Next time I'll take pictures as I sew and it will be a lot easier to explain.
Oh, and you could easily leave out the panels on the side if you wanted.
If anyone makes a shirt with this, I would love to see it
And Mivzi, I used this to make the last one: http://www.craftster.org/pictures/showphoto.php?photo=218126&ppuser=167159
I'm sorry, I forget where I found it.
These are the pictures I took while making it, I did it quite a while ago:
If you have any questions, just ask
Hope that helps! (and isn't atrociously confusing....)
