Wreath making - on the cheap

Normally I buy polystyrene rings for the base of my wreaths.  However, the more wreaths I made the costs were beginning to add up.

I decided to consider more cost effective options for the base of the wreath.

I had read on blogs about people using pool noodles from the dollar store for their wreaths.  

You can't really find pool noodles here in Ireland so I considered the alternatives.

I went to Woodies DIY and bought insulation tubing for pipes.  It was only 1.49 euro for a strip!! I cut it in half and taped it in a circle.

A wreath base for 75 cents in comparison to 3.50 euro.

Every year there is a sale of crafts in my workplace for charity so I am currently working on wreaths for this.

Do you have any alternatives to polystyrene rungs?
