There are a number of different ways to achieve your goals. What sort of home printer do you have? I am most familiar with Laser printers, but Inkjet printers can also print directly onto fabric. Was back around the 2000s I used to do a lot of printing directly onto fabric which had been ironed onto freezer paper, that is not even a specialty printer sheet. Depending on what you have as the printer there may be different treatments used.
You can also buy fabric sheets, I find the prices are MUCH lower at like an Office Depot than the quilt shop. Should be large envelopes of sheets in the specialty section. Again, make sure you get the right product for your printer.
Using the graphics of handwritten notes, you might have to reverse the image (part of the print options) to have it turn out ok.
A number of posters here have had very good luck with Spoonflower and similar sites.
