I know that this may not be the first on this subject but maybe I can share some ideas not covered by others.
If you like my effort here please take time to rate it.
Step 1: What you will need to get started
Step 2: Prep the plastic bags
First I cut the bottoms off the bag.
Next cut the handles from the top of the bags.
I then cut up the side of the bag and open it up.
Next, cut the logos and any other ink from the bag. If you leave the printing on it will be difficult to add color and graphics later that stand out.
Now cut strips from the bag by making vertical cuts every 1.5 to 2 inches apart.
I like to place the different types of colors in separate piles.
*** Although I have yet to try this tip out myself one thing you can do is cut 3in diameter circles instead of strips. It would give the bag a different look altogether. DonÃ¢â¬â¢t be afraid to experiment with new styles!!!
