How to Crochet Fruity Pot Holder 1 - crochet Orange Coaster (lovely result with felt) 

Thank you so much for your lovely words. God bless you too 🤗

It's the basic increase method. Row 5: (3dc, increase) x 12 times. Row 6: (4dc, increase) x 12 times. Hope this clears up your doubt

Yes it did thanks

It's a black felt. It's sewn onto the coster for stability and weight and doesn't necessarily stick to the table. I mean it's not sticky.

Thank you so much. Point duly noted 😊

Exactly the across white part that i was looking for to see in the video, to learn it, was rushed and not explained :/

Hi Hanina Hani, I'm so sorry about that. You can watch this short video here to learn that surface slip stitch. It's exactly the same, please do give it a watch. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SLh5bumoabg.html
