Little Baby Filet Crochet Set
Space = Open Block should read: ch 2, skip 2 dc, dc in next dc
There should be 2 dc at beg of Row 3 (beg ch-3 counts as first dc) and 3 dc at the end (the first dc of the 3 at the end is part of the preceding open block of ch-2, sk 2 dc, dc in next dc.) On Row 3, after the last 3-dc solid block is worked, you will skip 2 dc then work 1 dc in next dc (to complete the open block), then work 1 dc in next dc and 1 dc in top of turning ch, equaling 3 dc at the end of row.
Row 3 of the chart is a bit unclear because the extra dc that are part of the Open Blocks are not shown (apologies for the less-than-wonderful chart, it was made several years ago so the graphics are not the best).
The number of dc at each end of each row will vary from row to row. Once you get it set up it should be easier to follow blocks & spaces :
Row 4: 6 at beg, 5 at end
Row 5: 5 at beg, 6 at end
Row 6: 6 at beg, 5 at end
Row 7: 5 at beg, 6 at end … and so on and so on …
