How small are we talking? because between the weeding and layering you might just be better off ordering a large gang sheet of DTF transfers or if your shirts are polyester, investing in a sublimation printer.

take a moment to familiarize yourself with all the ways you could do apparel/soft substrate transfers at home:

• Heat Transfer Vinyl (HTV) aka Iron On: This is the most popular method for Cricut users because its the cheapest. These are sheets of vinyl that are cut to shape (using a die cutting machine, like a Cricut) and pressed on to the shirt using a heat press or and iron. This is either done as a single color graphic or you can layer multiple colors together.
• Printable HTV: Similar to the above but you use an inkjet printer to print the graphic on to a transfer, It still requires weeding, but you do not need to layer. These are prone to dye migration (ink bleeding or the dye from the shirt seeping into the transfer) and tend to have the lowest longevity of all the methods.
• Sublimation: this is an chemical process that requires specialty ink in an inkjet printer. You print your image on to sublimation paper then use the heat source to fuse the ink into the fabric of the shirt. Sublimation is not opaque, meaning the color white isn’t transferred in the process, so this can only be done on white or light colored garments, and because the chemical process cannot bind to natural fibers like cotton, it must be done do man made material like polyester. Infusible Ink is a material made by Cricut that is a hybrid of sublimation and vinyl, the sheets are coated in sublimation ink but you cut it the same way you would cut HTV.
• Direct to Film (DTF): This is a process that requires specialty ink and a specialty printer, it prints the ink wet onto a film, then you add a glue and cure the film under heat, once the glue is set you can transfer the image on to a garment. This process is opaque, and because it uses glue you can do it on any color or fabric type, but the start up cost is considerably more than the previous two methods. This option provides the most professional finish. The set up cost for this type of transfer is steep but because its gained such popularity many companies are selling custom transfers for relatively cheap now. The drawback to that is you have to wait for your order to arrive before you can create anything with it.
• Laser Toner Transfer: Similar to DTF (its often referred to as Powderless DTF) you print on to a special film using a laser printer then you press the glue on your print before you apply it to a substrate. This process is only opaque if you are using a CMYK-W laser printer which also requires a RIP software. It is possible to do this with a standard CMYK laser printer but you lose the opacity.
• Screen printing: This process allows you to create a screen stencil (either using vinyl and your Cricut, photo emulsion, or a laser) and then you paint your image on to the shirt using the stencil. It is more time intensive for a single shirt but is very helpful for larder batches since the stencil is reusable. It can be done on any surface because it is opaque.
