When making these jackets is there a certain sweat shirt that you prefer to use? Has anyone used the joeboxer shirts from kmart?

I never have, so I'd be interested in knowing, too. I might want to make one for my dear, sweet mom:-)

I prefer 100% cotton for these :D:D:D

I like Jerzee brand or Hanes They are cut full.

When making the shirt do you use a shirt that is the same size as you would normally wear or use one that is a size bigger?

I was wearing a sweat shirt the other day and decided I didn't like it as the bottom cuff was too tight(couldn't be me, could it?) anyway, will be perfect as a coat. Can't wait to start it but have to finish a quilt first.

You can use size that you wear. If hou like looser fitting jacket the go up one size.
Have fun. I always to a stay stitch before cutting off bottom or top bands also befor cutting cuffs off. This stitching will keep shirt in shape.

I went one size up because I cut the seams and cuffs off rather than seam ripping them open. And I ended up with a much too large jacket that I had to cut down. But I would rather have it too large than too small.

I usually go 1size up, pick up sweatshirts whenever I find a good sale or clearance.. Just buy 100% cotton, brand doesn't matter to mme as much as that.

I also use denim mens shirts, they make nice jackets..

I always go at least 1 size larger and sometimes 2 sizes because I like them loose and usually have a sweater on under it also.
