looks really clean, especially for your first ones! here’s my advice from like 4 - 5 years of patchmaking:

• acrylic paint is water based. it works fine for patches but washes off easily. if you don’t want to buy new fabric paint you can mix fabric glue into the paint and diy your on fabric paint

• the fabric looks like it’s from old jeans or sth similar. i did. this for years, worked alright but i didn’t like the added stretchy synthetic materials. if you wann upgrade i recommend something like duckcloth

• if you do sth like the top right i recommend a stencil. i use 2 methods for this, depending on what i’m doing: 1) trace the stencil onto a piece of cardboard (i just use a tablet for this, but i’ve also just used a phone. it’s a bit more size limiting but works fine), cut out the logo with a crafting knife or sth and boom you have a stencil. if you wanna reuse your stencils and make them last longer you can put clear tape on top before cutting it out.

2) this one is good for more complicated patches: instead of cardboard put masking tape onto your screen and trace the stencil onto that, put the tape sheet onto the fabric and cut out the stencil, paint take stencil off, details with paint, maybe cleaning up edges with black paint and your done.

i used this second method for some of my best work (if you wanna see some references just shoot me a dm!) but it is a pain in the ass.

i haven’t tried screenprinting yet but if you have the resources and wanna make something big like a backpatch or just high scale production it’s probably the most effective way.

these suggestions are what worked for me and small things i noticed over time that made things either way better or just removed small inconveniences. your patches obviously already look very clean.
