I made these potholders for my grandmas for Christmas. I didn’t really follow any pattern, I just cut two 20cm (8 inch) squares out of leftover fabric and sandwiched them with two layers of thermolam (Vlieseline 272). For the pockets I used either rectangular 13×20 cm scraps or triangular pieces half the size of the square and quilted them onto one layer of thermolam.
The only hard part for me was attaching the (selfmade) bias binding. Since this was my first try ever it came out rather wonky (especially the hanging loops). But I decided I dont care- they’re potholders, not wedding dresses.
