Video Tutorial: How To Crochet Hearts on Blanket
Come along as I make this mosaic crochet heart pattern and see just how easy it is in our step-by-step video crochet heart basket tutorial.
Crochet Heart Blanket Pattern Materials
- A 5mm(H) crochet hook or hook needed to meet gauge
- Scissors
- Tapestry needle
- Stitch markers
Along with the above you will need the following yarn for your blanket:
Herrschners Worsted 8, 100% Acrylic, (489yds/448m/226g).
I used 4 colours for my blanket but you can use as many or as few as you like! The amounts shown are using A as the main colour, then the other 3 colours (B, C and D) almost evenly as shown.
You will require approximately 1230 metres, 1345 yards of yarn A to crochet the blanket. 3 balls of the recommended yarn A.
You will also require approximately 345 metres, 375 yards of yarn B and C, and 300 metres, 325 yards of yarn D. 1 ball each of the recommended yarns B, C and D.
It’s a category 4, worsted weight yarn which is what gives the blanket is cosy feel. Find out more about yarn weights and categories with our handy yarn weight chart.
For my blanket I used Herrschners Worsted 8 in the following colours:
Main Colour: A: Plum Wine
Contrast Colours: B: Aran, C: Lotus, D: Mauve.

- Brava Worsted by WeCrochet, 100% Premium Acrylic, 218yds/200m/100g
- Starlette, 100% Acrylic, 180yds/165m/100g

Special Stitches
SINGLE CROCHET (sc) always worked in back loop only (blo).
Insert hook from front to back through back loop of stitch to be worked. Yarn over and pull through stitch. Yarn over and pull through both loops on the hook.
MOSAIC DOUBLE CROCHET (Mdc)
Yarn over and insert hook into front loop of stitch two rounds below. Yarn over and pull through the stitch. Yarn over and pull through two loops on the hook.* Yarn over and pull through remaining two loops on the hook.
The stitch behind the Mdc on the current round is left unworked.
MOSAIC DOUBLE CROCHET 2 TOGETHER (Mdc2tog) – current and next st
Begin working a Mdc in the current st but stop at *. Now begin another Mdc in the next st and complete by yarning over and pulling through all the loops on the hook.
MOSAIC DOUBLE CROCHET 2 TOGETHER (Mdc2tog) – previous and current st
Begin working a Mdc in the previous st but stop at *. Now begin another Mdc in the current st and complete by yarning over and pulling through all the loops on the hook.
2 MOSAIC DOUBLE CROCHET (2Mdc)
Work two mosaic double crochet stitches in the front loop of the stitch 2 rounds below. In the heart motif this helps to shape the sides. It does not increase the stitch count as you will be skipping a stitch either before or after.
FOUNDATION SINGLE CROCHET (Fsc)
- Step 1: Ch 2, insert hook into second ch from hook, yarn over and pull up a loop. [2 loops on hook]
- Step 2: Yarn over and pull up another loop i.e. ch1. This creates the first “chain” in your foundation row. [still 2 loops on hook]
- Step 3: Yarn over and pull through both loops to complete the first Fsc.
- Step 4: Next stitch and subsequent stitches: Insert hook into “chain” created in Step 2 (step 5 on subsequent stitches), yarn over and pull up a loop. [2 loops on hook]
- Step 5: Yarn over and pull up another loop i.e. ch1. This creates the next “chain” in your foundation row. [still 2 loops on hook]
- Step 6: Yarn over and pull through both loops to complete the next Fsc.
- Repeat Steps 4, 5 and 6 as required.
How do you Make a Heart Stitch Crochet Blanket?
- The Blanket is made from the bottom up in rows.
- The yarn is broken at the end of each row.
- The next row always begins with the right side facing, starting in the first stitch.
- The Blanket is made using the overlay mosaic crochet technique.
- Once the Blanket panel is complete, you can either create tassels from your ends or weave in your ends to finish.
Pattern Gauge
Gauge: 15 sts and 15 rows = 4″ by 4″ using 5mm hook
Making a gauge swatch will help you find out if your yarn and hook size will give you the tension for the blanket.
Before you jump into crocheting your modern crochet heart blanket pattern, take a moment to read through the pattern notes—it’s a game-changer!
These handy insights will not only simplify your pattern-reading journey but also ensure a smoother crochet experience. You’ll find helpful tips on deciphering the sizing, customisation and more.
Trust me, a quick peek at these notes will set you up for crochet success!
- The pattern is worked in rows using the overlay mosaic crochet technique for the Main Blanket Panel.
- The Main Blanket Panel requires you to break your yarn at the end of each row, then with the RS facing rejoin your next colour of yarn in the first stitch of the row just worked.
- All stitches in the Mosaic Sections are worked as sc in blo or Mdc, except for the first and last st of each row.
- The first and last stitch of each row are worked as a single crochet through the full part of the stitch.
- Each Row uses just one colour.
- A ch1 at the beginning or end of a row does not count as a stitch.
- Read through the entire pattern before beginning.
- Make sure that you are familiar with all of the stitches in the abbreviations list before you begin.
- Stitch counts are given in [ ] at the end of each row. If no stitch count is given, then the count is the same as the previous row.

If you are making the blanket the same dimensions as mine:
Rows 35-146: Rep the Main Set Pattern.
If you’d like to match my sequence in the images, then do the following:
First, last and all even numbered rows = A
Rows 3-19 (odd rows) = B
Rows 21-35 (odd rows) = C
Rows 37-51 (odd rows) = D
Rows 53-67 (odd rows) = C

You can of course use any colour sequence you like and repeat the Main Set Pattern any number of times until your blanket is the size you need. When you are ready, complete by following the final 3 rows.
Fourth Section: Final 3 Rows
Row 147: CC: Rep Row 19.
Row 148: MC: Rep Row 20.
Row 149: MC: ch1, sc in each st across.
Once complete block the blanket lightly and then you can either weave in your ends as I have or create a tassel border as follows:
With the RS facing you, gather approximately 6 tails at a time and secure into a simple knot. Repeat this process along both sides of the blanket. Trim the tassels to the length of your choice.
