I started with a jumper for me, made using the Sew House Seven for Simplicity 8529.
You can see from the photo below that the cuffs and bottom band are cut the same size as the section of garment they are attached to, as directed by the pattern pieces. Depending on your fabric / ribbing, you may prefer to reduce the length of the ribbing so that it stretches as it is attached.
My scraps were smaller after this projecr, but I managed to put together a pair of Trigg shorts for my hubby, just changing the pockets to be patch pockets on the front, and leaving them un-hemmed..
I did have enough scraps left over to make a pair of shorts for my son, only my daughter came in and saw all the fabric bits laid out and decided that she'd like to make a pair of shorts for herself. Which she did, but I don't have photos to show you.
Now I only have straggly scraps left, but they are the mostly from the fabric with the moose print, which I love, so I am still hesitant to throw them out.
