The Nine Patch Parade Starter Set includes six 8.5 x 11 inch pattern booklets (12 to 20 pages each) and 2 Nine Patch Rulers that make 3-inch and 4-inch Nine Patch blocks. The "no math" Rulers combine accuracy with strip techniques. Each pattern includes details for making a quilt that can be easily completed in one month, plus additional designs and info for making other versions. The information contained in the pattern set adds up to a great resource for "all things Nine Patch." Patterns are not sold separately and are only available in the Starter Set. No substitutions.
