They are sometimes also called slopers, although purists will argue that a block and a sloper are different things.
Blocks are typically not made as-is but rather serve as a basis for other patterns so the instructions below will not go in depth about closures or finishes and are for the default Titan block.
- Join the outseam (the seam that runs along the side of your leg) of the front and back.
- Join the inseam (the seam the runs along the inside of your legs) of the front and back.
- Du hast jetzt ein Bein. Wiederhole die Schritte für das andere Bein, **und stelle dabei sicher, dass die beiden Beine Spiegelbilder voneinander sind**.
- Turn one leg with the good side in, and the other with the good side out.
- Now tuck the *good side out* into the *good side in* leg, so that they have their _good sides together_.
Keep an eye out for anything you keep doing whilst wearing the mock-up, are you pulling it down? Constantly adjusting the shoulder? etc. Things like these are signs of where the pattern may need adjusting.
Sometimes you may need to wear the mock-up for an extended amount of time to get a better sense of the fit so don't be afraid to walk around in it for a couple of hours.
It is best practice to make a paper pattern from the mock-up if you have made any alterations, as this will allow you to clean up any lines but also means you have a pattern that you can keep producing garments from.
