So, I think I can sew?

These last few days, it seems that I've been bitten by the sewing-bug... :/ I've been sewing almost three-days straight; about an hour at most each time. I've made three things, a jsk, a bolero cardigan, and a blouse/cutsew/okay, it's a frilly shirt! All without the slightest idea of what the crap I was doing other than that I had a design in my head and, twice, I created what I imagined. I AM CONFUSED. I mean, I know that I'll sound like I'm bragging, which of course, I kinda am, but...I seriously am confused. How am I doing this?! D:

Lemme just show you what I mean:

One: IT ACTUALLY FITS! How did this happen?

Two: Behold my attempt at a peter-pan collar!

Three: The creepy thing, the lace I used/found is the same lace that my Bodyline l140 skirt has.

Looky-loo~ ^ The lace!
And NOW looky-loo below.

Now, I also made an ill-fitting jsk out of some lovely fabric:

And a bolero cardigan as well after a couple days:

Note, I did NOT make the jsk in this picture

Sooo~ I THINK I can sorta sew...I mean, I know I need practice, but... Yay? ^^;
