I once had a free pattern, it seemed a lot like this one, but there were blocks around each heart, and the side edges of each heart were cut off by those blocks- does that make sense? It seems to be a mix of these two patterns. Any help would be greatly appreciated. Thanks

This one is charted so I think adding more purls around the heart itself might work; just mark them on the chart and knit it as amended. Was your pattern heart motif blocks in rows and columns like this one or staggered or ???
