Good morning Ladydanana,
Thanks for your question and welcome to the community!
I believe you are referring to the Garden Club post on our site here entitled: Craft a Festive Holiday Wreath.
In that post, the project calls for various PVC sizes, so depending on what sizes you want will determine how it will be used.
Most PVC pipes come in 10 foot sections, but you can get shorter lengths by Charlotte Pipe at your local store.
View the link above to see various lengths and diameters to get the correct pricing to complete your wreath.
