hi Danny! thanks for asking lol and thanks for everybody else's input i am finding this very helpful. because i'm a beginner, i wanted to practice punching with some sort of target in front of me so that it's not as hard to imagine an opponent in front of me, made of thin air... which at this stage of my training is hard to do.. i guess i'm more of a kinesthetic learner. so being able to feel, touch and sense things can help me to learn better, espeically because i find the hand techniques far more confusing than kicks (dance and yoga experience both taught me to do complicated steps but not so much with arms they're mainly there to look pretty in dance and mostly holding a stationary pose in yoga). i would also like to practice accuracy with kicks because im at a stage where i can't really kick with enough muscle control to precisely hit a target, or even part of a target lol! and again with the imaginary opponent thing... my dojo has a no white belt sparring rule that i think is really good, so i wont need to worry about that till much later. which also means i get plenty of time to get good at 1 simple thing at a time, which is also my learning style... horrid at multitasking unfortunately
so mostly for practicing with something in front of me and for accuracy of strikes and kicks, and if its a proper bag i guess i can just start to get a feel of what hitting something feels like because i havent actually hit much of anything before lol!!! that proly sounds silly now that i've said it lol but i only have 1 x 1hr class where sometimes they use pads for practicing on but the other classes are beginners classes that's just practicing the really basic techniques. i am literally an absolute beginner...
thanks again for those who suggested the kung fu bag and the sleeping bag i actually tried stuffing towels n stuff into a pillow case and punching it lol it goes flat very eazily hahahaahahahhaaa ...but better than nothing! i'm going to ask to borrow a sleeping bag to try too

i saw a few kung fu bags too online but are they flat against a wall? would i hurt my hand i have no idea how thick they are
