That's what made me decide to build a Great Pumpkin costume this year: no limits!
It should be noted that I don't embark on these projects with a really specific plan. I make stuff up as I go along, so I don't have real patterns to follow. These are descriptions of my efforts, and I hope they give you all some interesting ideas for costumes that might interest you! Here's a list of some of the stuff I used to make this costume:
Lots of thrift clothing, cut up for patchwork
Two spools of button thread
About seven bunches of embroidery thread
Leather scraps (from a Crate & Barrel sample book)
Fake leaves (some purchased from a craft store, most from a couple of "autumn garlands" found at a thrift shop)
Three or four yards of fabric with patterns that I liked.
One black satin sheet
One sheer orange curtain
One pair of black corduroy pants
One pair of gloves
One spool of wide orange ribbon
One fuzzy orange blanket from Bed Bath & Beyond, on clearance
One yard of fun fur
Copper napkin rings
One kimono and obi
Long-sleeved green thermal shirt
A NOTE ON HOW I SEW:
I don't have a sewing machine. I don't even know how to use one. So everything I have done here is done by hand.
This is neither a boast nor a complaint, just a statement of fact. What I'm getting at is: YOU DO NOT NEED TO KNOW HOW TO SEW IN ORDER TO MAKE THIS OR ANY OF MY OTHER COSTUMES!
I create a pattern through eyeballing, and rough estimation. If I need to be more careful, I sketch out a shape on newsprint to get it close to what I want. I build a costume with a liberal use of stick pins and strong button thread. If you know how to sew, this should be a breeze! But if you don't, oh well! Don't worry about it! You don't need it!
