As a newcomer to MACHINE sewing...All I can say is,GO for it!
I bought a cheap Janome machine,it will do all I need for now. Less than a 100 bucks,seems to be great quality for the money.
I have made stuffsacks,patched packs,bags,etc.
My next project is making a quilt for my buddy out of his 30 year old bag.
I just picked up an old DRESSMAKER machine for 20 bucks. Heavy steel rig that will do some heavy duty work. Put a belt on it and it is working just fine.
I am addicted to sewing now,and I do not have to beg my wife anymore.
I hemmed(spelling?)my first pair of pants this morning,I am free !!!
Sewing is only as difficult as you make it,anyone can do the basic stuff. It is mostly common sense and a few tricks.You just need to think things out in advance. My wife was amazed at some of the ideas I came up with,not like I am a genius. Like I tell her...I don't mean to make sense...but....and then she tells me to shut the hell up.
