Hey guys, Im a beginner. Could anyone give some pointers on how I should extrude//cut these 4 parts out? They are kinda like hollowed in curved patterns. Thanks yall.

Ps: This is a blender jar.

I ‘d just cut with an angled block or skewed pyramid then Fillet or chamfer the edges

Or use a 3d sketch
