I'm quite a noob when it comes to Sketch still, but I often use it for quick edits of images etc.

Now I want to create a customized mask for use in social profiles for my music. I want it to be a circle with triangles pointing to all 4 corners. But when I'm trying to mask, only one shape gets used. Even if I select all 5 of them. I tried exporting it as a png, but then I'm unable to use it as a mask.

Any suggestions on how to do this?

Combine the objects (four arrow shapes) into a group Command + G, then select the grouped objects and use the Union button or Option + Command + U in the toolbar to make them one shape:

Step 1: Group the separate Objects Grouping objects

Step 2: Selecting Objects and Select Union in Toolbar enter image description here

Combined shape -The combined shape

Step 3: Drag the shape you want to mask above the newly combined shape Drag mask below the shape you want to mask

Step 4: Select Mask in the toolbar Final mask
