I have beaded a few heart shapes in the past, using a single color of bead and a different method, but this time, I'm using a stitches method, and I also tried to mix two different colors of beads.
The result came out different and very beautiful.
Materials used:
✓I used two of my favorite seed beads, milk color and deep red.
✓0.3 fishline, scissors, and a beading needle.
To see how I did it, please come along..
Step-by-step Process
step 1:
I started by putting one red and two milk-colored beads on my 130 cm fishing line, which I had already threaded on my beading needle. I tied two knots, leaving a little bit of tail on one side, and then passed my long fishing line through the first milk-colored bead.
Step 2:
I put one MC (milk-colored bead) and one red bead on my needle, then passed it through the back of the same bead where my needle came out in Step One.
Step 3:
I let my fishing line come out on the next MC bead, put one MC and one red bead on my needle, and then passed it through the next two red beads.
Step 4:
I put one MC and one red bead on my needle and then passed it through the next three MC beads. 
Step 5:
I just snuggled the beads, and it gave me the base of the heart; I added two beads to it.
Step 6:
I put one red bead on my needle and passed it through the last bead.
The base is now well built. 
Step 7:
I continue to build on the base by putting one red bead and one MC bead on my needle and passing it through the next bead.
Step 8:
I put one bead on my needle, ignored the next two beads, and passed it through the next two beads.
Step 9:
I put one MC bead and one red bead on my needle, then passed it through the next bead. 
Step 10:
I put one red bead on my needle, ignored one bead, and passed it through the next bead.
Step 11:
I put one red bead on my needle, ignored one bead, and passed it through the next bead.
Step 12:
I put one red and one MC bead on my needle, then passed it through the next bead.
Step 13:
I put one MC bead on my needle, ignored the next bead, and then passed it through the next bead.
Step 14:
I put one MC bead on my needle and passed it through the next two beads.
Step 15:
I put one MC and one red-colored bead on my needle and passed it through the next bead.
Step 16:
Using the red color, I continue to ignore one bead, then add one bead.
Step 17:
I put one red and one MC-colored bead on my needle, then passed it through the next bead.
Step 18:
I continue adding one MC bead to finish this line.
Step 19:
I continue to repeat steps 16 to 18 above until I have eight beads raised up on both sides of the heart.
Step 20:
I pressed the two sides of the heart to meet each other in the middle, then I would add one bead and then ignore one bead for each line. I did this for three lines. 
Step 21:
To bring the shapes close to each other, I would put one bead on my needle, then pass it through two beads, ignore one bead, and pass it through two beads again until the line is over. I did this for one line.
Step 22:
To end this line, I put one bead on my needle and passed it through the next bead, ignored one bead, and then passed it through the next two beads, as can be seen below.
Step 23:
To close the end of this part of the heart, I added a single bead three times and then passed my needle around the last four beads a few times to make sure the work was secured.
Step 24:
As I headed to the final part, I brought my fishing line out on the first red beads on the other side; then I started to close the hole. Just like I did with the other side in the steps above.
Step 25:
To make the heart stronger, I stuffed a piece of nylon inside and then finished up closing the second side of the heart.
The final result—do you like it? 
Aside from attaching it to my bag, it can also make a great pendant or a keychain.
The end
Thank you so much for your time and support. 🙏❣️
