here's the deal:
you'll need scissors/x-acto knife, shelf liner, fabric (for backing), and an embroidery hoop. i had all these things on hand because i buy fabric and embroidery rings like no one's business.
cut out the pattern you like. i knew i wanted mine to kinda grow up from one side so i had that in mind when cutting.
place fabric in embroidery hoop, peel shelf liner and adhere to fabric. i actually had to add glue because my liner fell off after a bit.
