This is the how to on the Santa Pants on the right.
I saw something like this at my LSS where they were selling this "kit" and I thought I can figure this out so here is my version. This is using a quarter sheet of 8 1/2 x 11 CS but can be adjusted to any size you need. It is basically your 2-4-6-8 box in a smaller version. It's just that you need 2 of it- one for each leg.

Take a quarter sheet of paper 4 1/4 x 5 1/2 and score at 1/2, 1 3/4, 3, 4 1/4 as shown, the score the bottom across at 1 1/4 inches- Just make the bottom scoring whatever the width of the box would be. Cut the silver marked lines and cut out that little 1/2 x 1 1/4 corner if you wish. You will need 2 of these in real red CS. ( I used white here to better show you the numbers and scoring lines) Fold into 2 boxes.

For the santa's pant cuffs, I thought of using felt and other dimensional fabric but I wanted to keep it totally SU so I did faux suede technique here.
Another crimper use- take a 3/4 " strip of whisper white CS and run it through the crimper a bunch of times until the fibers separate and then peel back to reveal the softer suede like center.

like this. If it separates unevenly, try separating from a different corner.
Tape the faux suede onto the bottom of the pant leg boxes and tape the 2 boxes together to make the actual pants. Try to put the seams on the inside to make it nice and neat.

For the belt I used a 3/4 inch strip of brushed silver CS. I drew 2 horizontal lines about 1/8 inch from the edge then put a line every 1 inch increment to separate out each buckle then put shorter lines about 1/4 inch from the edge. It seems like a lot of work but try to punch out the small slots with a small piece of paper- IMPOSSIBLE! It is much easier to have a long strip you can slide in to punch the holes in the buckle evenly as shown. For the last two left on the striip, punch holes on both sides

before cuttings the two buckles apart. Now you have the buckle.
Take a 8 1/2 inch wide black CS and cut a 3/8 inch black strip. Run the black strip through the belt buckle as shown on the sample and tape down as shown.

take 8 1/2 wide paper and cut 3/8 inch strips in red for the suspenders and place 2 sticky strips on either end as shown.

Tape the red strips in the front on either side of the buckle straight up.

then angle the strip and tape down in the back to create the criss cross in the back as shown.

Finished pants. Fill with Hershey's kisses or other goodies- candy canes, etc. You can use larger paper - half sheet and score at 2-4-6-8 and bottom at 2 inches to make a bigger box or use a whole sheet- score 1/2 inch to tape down- that leaves you 10 1/2 inches, divide by 4 - so 2 5/8 on each side and across the bottom. This makes for a really cute center piece. Finally all my math skills coming in to full glory!
I will do the Missus Santa tutorial tomorrow.
I am too wiped to think....
