This is a pattern only. If you click on the title under the picture you will see a tab that says "supplies" This will show the suggested flosses and the amount required. In this case you will need one of each color. If the pattern requires more than one skein that will be indicated in the middle column. You can purchase all of the supplies at the same time you purchase the pattern. You DO NOT have to purchase all of the flosses if you have a stash. Buy them all or buy what you don't have.
