Learning to sew

so you thread the top part.  The thread from the top goes through the needle, then through the foot and just pull it towards the back.  Then to get the bobbin thread up what you do is put your bobbin in and have some thread of the bobbin coming out the little door of the bobbin compartment and going to the left of the machine.  Then with the top already threaded, use the hand wheel and make 1 stitch, no fabric just air.  and as the needle is coming up just pull a little on the top thread.  Keep raising the needle and pulling on the top thread until a loop of the bottom thread comes up through the hole.  Then take a small object, I use a seam ripper, and pull the loop out to the back, then pull on whichever direction of the loop is towards the end until you get the entire end of the thread, then pull the top and bottom threads to the back of the machine.  You should be ready to start sewing but I always use a test piece or a little crap piece of fabric to check that I did it right and it is working good.  That way you never fuck up your hoodie.  Good luck.

I'm producing an official tut, so hopefully I can help you very soon.

those helped a lot

does anyone know where to get like beenie fabric or something??

for hats? most stores won't sell that

im looking for that same kind of fabric... so doe companies knit those kind of hats or what?

most beanies would be made in a tubular shape, so their fabrics/products are specially made by manufacturers. you should ask you fabric stores if they have, but i really doubt it. it's unlikely this would be available to the average person because it's not really in high demand by at home sewers...

could i knit the hats? is that how they are done by companies

how much fabric do i approximatly need to make 1 sweat shirt...

2.5 meters of sweatshirt material is what I recommend.

you could knit a hat for sure, it's one of my hobbies. it just won't look like most smaller gauge knit hats they sell. mass production retail beanies are knitted but by a giant machine that works stupid fast.

so would if i used a cheaper knitting machine

no...just knitting needles or a different fabric

I just realized something while making my hoodie, how the fuck do you sew two pieces together that are curved? Like if I want to sew a half circle onto the front, how the hell do I sew it on correctly?

you mean to curves that go in opposite directions?
it's just a matter of going about it carefully, aligning about 1-2 inches of the section at a time, and walking your fabric cautiously. you could also very carefully pin it, but pinning all matching anges together, then again walking the fabric into place and pinning again. this is a good example to explain this complicated explanation!

Thanks a ton, I found a little tutorial on google too, but I think I'm gonna save this for my second hoodie haha. I don't want to do anything too difficult for my first hoodie.
