Cutting fabric on the bias allows for more stretch and drape in the material. This is because cutting on the bias means cutting at a 45-degree angle to the grain of the fabric, which allows the fabric to stretch and drape more easily. The benefits of cutting on the bias include creating garments that fit better, have more movement, and drape beautifully on the body.
A "knit" fabric will stretch, either side to side and/or up to down, but a "woven" fabric will not stretch.
While Bondaweb can be used on shiny stretch fabric, it is not recommended you do so, as the results may not be as good due to the fabric's elasticity.
That will depend on the fabric. Some fabrics stretch in only one direction while other fabrics stretch in both directions (like polyester double knit). You will need to check your fabric to determine the maximum stretch.

"Cutting on the bias" means cutting fabric at a 45-degree angle to the straight grain. This technique allows the fabric to have more stretch and drape, making it more fluid and flexible compared to fabric cut along the straight grain.
Twill is fabric that has a diagonal pattern. It is actually woven in such a way as to create diagonal "ribs" in the fabric itself (not just colored diagonal lines). Think of cordoroy - that is a fabric with a vertical (up and down) pattern woven into it. Twill is diagonal weaving. If a twill fabric has extra "give" so that it can expand (stretch), it is a stretch twill. Stretch twill often refers to the fabric having a small percentage of lycra/spandex in it, usually 2-4%.
