i have used quiltsmart pattern kits for numerous quilts- i've made 5 or 6 game quilts- 3 mariner's compass quilts and at least half a dozen lonestars.
the pre-printed interfacing makes everything go together quickly and easily- with great precision-
just be sure to read through the instructions before starting- and look everything over so you are familiar - they tell you exactly how to cut the fabrics for a minimal amount of waste-
i had a 54" lonestar together in 3 hours one saturday morning
the interfacing stays in the quilt- so you do make fairly (heavy) quilts- but that's what i like so---
and the game quilts- all the kids in the family love their game quilts- i personalize them for each child- they are wonderful!
