Filet Heart Coaster/Square – FREE Crochet Pattern
Here is my first filet crochet pattern. It’s a heart you can use as a coaster or an afghan square. For this pattern, I used size 10 crochet thread, but any other yarn will work just as well.
Personally, I think this would look lovely in a cotton bedspread. I’m thinking of making pink and white hearts and then joining them together with a red thread. Or, one could do red and white hearts and then join them with pink or another color. The possibilities are endless.
A few notes on Filet Crochet:
= 1 dc, ch 1, 1 dc (the open block at the beginning of each row is made with a ch 4 and dc).
= 3 dc
= 1 dc, (ch 1, dc) twice.
= 5 dc
In other words:
- 1 white (or open) square equals: 1 dc, ch 1. Then at the end of the row, work another dc.
- 1 red (or filled) square equals: 2 dc. Then at the end of the row, work another dc.

Measurements
- 3.5 by 3.5 inches (After the edging, the width measures slightly more than the height. It is hardly noticeable if worked in crochet thread, but a thicker yarn will result in a greater difference making it somewhat rectangular.)

Very easy to follow
Lovely pattern!
But I don’t understand how the graph gauge works. Two red squares represent five double crochets, but in the photo a row of seven double crochets is represented by three red squares on the graph. How does this work?
Hi Wren, that is correct; three red squares would have seven double crochets. Two red squares, which you see on top of the heart, have 5 double crochets.
Think of it as a mesh where you work the entire pattern with a double crochet and chain one. But then, for the filled (red squares), that chain becomes a double crochet. So instead of (dc, ch 1), it now becomes (dc, dc) for each square.
Perhaps this might be a better way to put it.
1 white (or open) square equals: 1 dc, ch 1. Then at the end of the row, work another dc.
1 red (or filled) square equals: 2 dc. Then at the end of the row, work another dc.
Let me know if that helps or if I’ve only made things more confusing. Thank you so much. :)
