I have listed here the supplies you might need to start a crochet project. I hope that this list is complete and that you find what you are looking for here. All of these links lead to Amazon.com where everything is very affordable and probably cheaper than what you find in a regular craft store in your area.
1. Crochet Hooks
Here I listed both brands that I use, Boye and Susan Bates.
2. Red Heart Super Yarn (Regular)
This link has multiple colors you can choose from. They even have the multi-colored yarn here. You get 244 yards with this.
3. Red Heart Super Yarn (Jumbo)
There are also more color choices when you click on this link. This is a better deal for those who would like to make doll making into a business. You get 365 yards with this.
4. Red Heart Yarn (Sport)
There are only a few choices on Amazon for this type of yarn. You can use this yarn for those small details in your work.
I love these scissors. They are so convenient and they also have a cover to protect the tip. Also, you will decrease the chances of poking yourself as well.
8. Darning Needles
These needles are convenient for sewing your pieces together. These are metal which is nice because the plastic ones tend to break when making dolls that are more complicated. The link here is for the clover and chibi brands. Either one will work.
