Never to early to start on your fall decor.
You can make my Indian Corns by using this pattern.
You will need to know how to Rug Hook. I started with a library book. Used an embroidery hoop and I purchased an inexpensive rug hook off of Ebay. I purchased my monks cloth (swedish weave cloth) from the local fabric shop. I do believe that I found the wool from 100% wool clothes at the local thrift shop.
If you already know how to rug hook. Some tips you could use are hook very tight. Use a small hook as it is easier to put the hoop through your foundation cloth with a small hook due to how tight you hook. I suggest using Swedish Weave monks cloth in a brown color. You can find this online and in some of your local stores.
Have fun with your choice of colors as you can see you can use any kind of wool. You can also use my pattern for the husks or I have seen some use cheese cloth that was coffee or walnut stain dyed. This is a fun look too. You can use any fabric you have on hand for the husks. I was thinking that some patterned fabric could add a fun look.
Feel free to ask any questions.
