Let’s create a cheerful yellow flower crochet coaster! This project is a wonderful way to add a pop of color and handmade charm to your home, and it’s quite easy to make. As we’re making a functional coaster, using 100% cotton yarn is highly recommended for its excellent absorbency and heat resistance.

How to Make a Crochet Coaster with a Yellow Flower
This guide will walk you through making a flat, round coaster and then adding a simple, pretty flower on top.
1. Essential Materials You’ll Need
- Yarn:
- For the Coaster Base: 100% Worsted Weight Cotton Yarn (approx. 30-40 yards / 27-36 meters). Choose a color that complements yellow well, like white, green, grey, or even a soft blue.
- For the Flower: 100% Worsted Weight Cotton Yarn in Yellow (approx. 10-15 yards / 9-14 meters). A bright, sunny yellow will look fantastic!
- Crochet Hook: A 4.0mm (US G/6) or 4.5mm (US 7) hook. The goal is to create a dense fabric for the coaster so it can effectively protect surfaces. If your stitches look too loose, go down a hook size.
- Scissors: For cutting yarn.
- Yarn Needle (Tapestry Needle): Essential for weaving in ends and assembling the flower.
2. Basic Crochet Stitches You’ll Use
You’ll only need a few fundamental stitches for this project:
- Chain (ch): To begin your work.
- Slip Stitch (sl st): Used for joining rounds.
- Single Crochet (sc): Creates a tight, dense fabric, perfect for the coaster base.
- Half Double Crochet (hdc): A medium-height stitch, useful for creating the flower petals.
- Double Crochet (dc): A taller stitch, also used for petals.
- Magic Ring (MR): (Also known as Magic Circle). This is the best way to start a round project as it creates a perfectly tight center with no hole. If you’re new to it, don’t worry, an alternative chain method is provided.

Part 1: Crafting the Coaster Base
We’ll start with a classic round coaster using single crochet stitches for a sturdy foundation.
Abbreviations (US Crochet Terms):
- ch: chain
- sc: single crochet
- sl st: slip stitch
- MR: magic ring
- st(s):: stitch(es)
Instructions for Coaster Base (Using your chosen base color):
- Starting Your Coaster (Choose ONE method):
- Method A: Magic Ring (Recommended for a tighter center)
- Create a Magic Ring (MR).
- Ch 1 (this chain is for height and does NOT count as a stitch).
- Work 8 sc into the Magic Ring.
- Gently pull the yarn tail to close the center hole tightly.
- Join with a sl st to the top of the first sc you made. (8 sc)
- Method B: Chain Method (Easier for Beginners)
- Ch 2.
- Work 8 sc into the second chain from your hook (the very first chain you made).
- Join with a sl st to the top of the first sc you made. (8 sc)
- Method A: Magic Ring (Recommended for a tighter center)
- Building the Coaster (Increasing Rounds to Keep it Flat):
- Round 1:
- Ch 1 (does not count as a stitch).
- Work 2 sc in each st around.
- Join with a sl st to the top of the first sc. (16 sc)
- Round 2:
- Ch 1 (does not count as a stitch).
- *1 sc in the next st, 2 sc in the following st*. Repeat from * to * around.
- Join with a sl st to the top of the first sc. (24 sc)
- Round 3:
- Ch 1 (does not count as a stitch).
- *1 sc in each of the next 2 sts, 2 sc in the following st*. Repeat from * to * around.
- Join with a sl st to the top of the first sc. (32 sc)
- Round 4:
- Ch 1 (does not count as a stitch).
- *1 sc in each of the next 3 sts, 2 sc in the following st*. Repeat from * to * around.
- Join with a sl st to the top of the first sc. (40 sc)
- Round 1:
- Finalizing the Base: Continue this pattern (increasing the number of single crochets between the increase stitches by one in each subsequent round) until your coaster base is about 4-5 inches (10-12 cm) in diameter.
- Once your base is the desired size, fasten off your yarn by cutting it (leaving a tail of about 6-8 inches) and pulling it completely through the loop on your hook.
- Weave in all ends securely using your yarn needle.

Part 2: Crocheting the Yellow Flower
This simple flower uses a few basic stitches to create lovely petals. We’ll make one layer for this coaster flower.
Instructions for the Yellow Flower (Using yellow yarn):
- Start: Create a Magic Ring (MR).
- Round 1:Ch 1 (does NOT count as a stitch). Work 10 sc into the Magic Ring. Pull the ring tight. Join with a sl st to the first sc. (10 sc)
- This forms the small center of your flower.
- Round 2 (Creating Petals):
- Ch 1 (does not count as a stitch).
- *In the same stitch where you just joined, work (1 sc, 1 hdc, 1 dc, 1 hdc, 1 sc).
- Sl st into the next stitch.*
- Repeat from * to * 4 more times around.
- (You will have created 5 petals, each made of a sc-hdc-dc-hdc-sc cluster, with a slip stitch in between them.)
- Fasten off, leaving a long tail (about 12 inches / 30 cm) for sewing. Weave in the starting tail of the flower base.

Part 3: Assembly & Finishing
Now, let’s bring your coaster and beautiful yellow flower together!
- Position the Flower: Place your completed yellow flower directly in the center of your crocheted coaster base.
- Attach the Flower:
- Thread the long yarn tail from the flower onto your yarn needle.
- Carefully stitch through the center of the flower and then down through the coaster base.
- Make several small stitches in a circular motion around the very center of the flower, ensuring your needle goes through both the flower and the coaster base. This will firmly attach the flower. You can also make a few stitches through the base of a few petals to keep them from flopping too much.
- Final Weaving: Ensure all remaining yarn tails from assembly are securely woven into the back of your coaster. Trim any excess yarn very close to the fabric.
- Blocking (Recommended):
- Gently wet your entire coaster (with the flower attached).
- Carefully squeeze out excess water (do not wring!).
- Lay it flat on a clean towel or a foam blocking mat. Gently shape the coaster base into a perfect circle and softly arrange the flower petals. You can use rust-proof pins to hold the shape if needed.
- Allow it to air dry completely. Blocking will help your coaster lay perfectly flat and give your flower a beautiful, defined shape.

You’ve now created a wonderfully charming and functional yellow flower crochet coaster! It makes a lovely addition to your home or a thoughtful handmade gift.
