THE HA-HA APPROACH: Every time you reproduce an antique pattern, or use a traditional block, make sure you include at least one fabric authentic to that period. Case in point: if you're stitching a Dresden Plate quilt (popular in the 1930s and 40s), use at least one period feedsack for the wedges. This "ha-ha" fabric makes for an intriguing secret you may (or may not) want to share with others!
