Burlap is super cheap. I bought 2 yrds (I have another burlap project coming up) and only spent $4. For my purposes, I used just a yard and had some left over so you could probably go with 3/4 yard. Cut the burlap into 1-1/2" strips. I used my rotary cutter which cuts burlap like butter. No need to be precise or Miss Perfect here.
I wrapped the strips around a 12" straw wreath form using hot glue to secure the ends until the form was covered. Honestly, I love it bare in all its raggedness. The threads speak to me.
